The EPSC is listed to UL 1738 Venting Systems for Gas-

Burning Appliances, Categories II, III, and IV (480°F Vent

Listing) / ULC S-636 Standard for Type BH Gas Venting

Systems (480°F Venting Listing)

Under this category, EPSC in diameters 4” to 14” has

been determined suitable for venting of ue gases at a

temperature up to 480°F (249°C) from gas red appliances.

See Section 1.10 Clearances” for specic details.

1.5 GENERAL INSTALLATION REQUIREMENTS

When venting Category II, III, or IV appliances or TYPE L

vented appliance, Powerstack must be used for the entire

length of the system. Do not mix pipe, ttings, or joining

methods from different manufacturers

Refer to the gas appliance manufacturer’s instructions to

determine venting requirements and limitations with respect

to installation and use of the appliance. It is the responsibility

of the installer to contact local building and re ofcials

concerning any installation restrictions and/or inspection

requirements that may apply.

Permits may be required before starting an installation.

If required by the appliance manufacturer, a Drain Tee Cap

must be located as close as possible to the appliance ue

outlet. Depending on the arrangement of the vent, more than

one drain may be required.

Only one Category II, III, IV appliance shall be connected

into a venting system, unless the appliance manufacturer

specically approves a multiple venting system. Cat. II, III

or IV appliances SHALL NOT be common vented with Cat.

I, natural draft appliances. This limitation can be ignored

if an engineering analysis demonstrates normal and safe

operation of appliances.

Powerstack shall not be routed into, through, or within any

vent, such as an existing masonry or factory-built chimney,

that is connected to another appliance.

Any horizontally installed portion of the venting system shall

have a slope (upwards for Category II, III, or IV appliances

or downwards for Category III or IV appliances) not less

than 1/4 inch (6.4 mm) every 12 inches (305 mm) to prevent

collection of condensate at any location in the assembly; and

means shall be provided for draining the condensate.

Due to possible ice build up and blockage, it is required

that the proper sloping be employed when the vent is

installed in a horizontal installation. Refer to the appliance

manufacturer’s installation instructions for further details

regarding the installation of the condensate drain ttings;

A venting system that is mounted at the exterior shall be

enclosed below the roof line to limit condensation and

protect against mechanical damage.

After installation, the joints and seams shall be checked

for gas tightness when using the venting system with a

Category III or IV appliance.

1. GENERAL INFORMATION

1.1 INTRODUCTION

These instructions comprise both general guidelines and

special requirements for all parts in the product line. Before

specifying a design or beginning an installation please

carefully review these instructions.

Contact Local Building or Fire Ofcials About Restrictions and

Installation Inspection in Your Area.

1.2 FEATURES

The PowerStack EPSC are made for residential, commercial

and industrial applications. It is a factory made modular

stainless steel venting system designed for quick assembly.

All parts have a male and female end with an Elastomer Triple

Lip Seal.

The PowerStack is offered in a single wall version and is

available in internal diameters ranging from 4” (100mm) to

14” (350mm).The fully welded liner is manufactured from a

special corrosion resistant 316L PCM (Puried Chromium

and Molybdenum).

A pressure capability of up to 15”Wg (3,745Pa) and

condensate containment is achieved by using a Elastomer

Triple Lip Seal as part of a simple push-t joint design that is

held in place with a lever type locking band.

All Powerstack models (EPS, EPSA, EPSC, EPS1, EPS2,

EPS3 and EPS4) may be intermixed in the same venting

system, provided the proper associated airspace clearances-

to-combustibles are maintained.

PowerStack EPSC is suitable for negative, neutral or positive

pressure applications and intended for use in a variety of

applications including, but not limited to, Special Gas Vent for

Category II, III and IV.

1.3 SYSTEM DESIGN AND CALCULATIONS

Complete system sizing and capacity information may

be obtained from the “Chimney, Gas Vent, and Fireplace

Systems” chapter of the ASHRAE Handbook, from

the ENERVEX “Chimney and Exhaust System Design

Handbook”, or by contacting ENERVEX Technical Support.

In spite of any sizing guidelines, when sizing venting systems,

it is most important that the appliance manufacturer’s

installation instructions be followed.

Failure to follow these instructions may result in inadequate

vent system performance and/or a violation of the equipment

manufacturer’s installation requirements. Proper operation

of the venting system and appliance is dependent on the

use of all parts specied by the manufacturer for use in the

particular installation. The performance of the system may

be affected if the proper assembly of all required parts is not

accomplished.

1.4 UNDERWRITERS LABORATORIES LISTINGS

The ENERVEX PowerStack EPSC venting system is Listed by

010.8030.1222 12.22

1.6 TERMINATION

For EPSC systems used as Special Gas Vents, the systems

shall terminate above the roof level in accordance with the

following requirements:

• Five feet above the roof level or any adjacent at roof,

wall parapet or air intakes, and/or in accordance with

the following NFPA 211 requirements.

• Where vent terminates at less than 10 feet from

any adjacent ridge, wall or parapet, the vent shall

terminate at minimum 3 feet above the ridge, wall or

parapet.

• Where vent terminates at more than 10 feet from

ridge, wall or parapet, a minimum height of 2 feet shall

be required above the ridge wall or parapet.

Vent systems that exit the structure through a sidewall or

the like shall terminate in accordance with the following

requirements:

• Not less than 12 inches above the ground.

• Located above the snow line in geographical areas

where snow accumulates.

• Not located in trafc areas, such as walkways, unless

the venting system is at least 7 feet (2.13m) above the

ground.

The installation of the venting system relative to appliances

that incorporate combustion air inlet systems shall have a

venting system that terminates:

• 6 feet (1.8 m) or more from the combustion air intake of

any appliance

• More than 3 feet (0.91 m) from any other building

opening, gas utility meter, service regulator, and the like.

• Less distance if specied in the appliance’s instructions.

The venting system shall not be routed into, through, or

within any other vent such as an existing masonry or factory

built chimney ue (exception: a masonry chimney ue may

be used to route the venting system if no other appliance

is vented into the same masonry chimney ue and the

installation instructions specify such restrictions.

For EPSC venting systems used with Category II and III

appliances, the vent must terminate at least 3 feet above the

highest point where it passes through a roof of a building

and a minimum of 2 feet higher than any part of the building

with a horizontal distance of 10 feet. There are exceptions to

these requirements when a mechanical draft system is used

and some listed appliances have other requirements, so it is

recommended to consult with the authority having jurisdiction

for actual requirements.

1.7 SURROUNDINGS / ENCLOSURE

PowerStack vents are primarily intended to be used in

re resistive, noncombustible surroundings or installed

unenclosed.

Where the vent extends through any zone of a building

outside the area in which the heating appliance connected

to it is located, it shall be provided with an enclosure having

a re resistance equal to or greater than the re rating of the

oor, ceiling, wall or roof assemblies through which it passes.

All PowerStack models may penetrate a combustible roof

using either the Insulated Roof Assembly or the Ventilated

Roof Thimble. These are the only parts intended for use with

combustible construction. All other parts, such as Plate and

Wall Supports, and Floor and Wall Guides, are for attachment

to non-combustible construction.

Where, according to local code, no chase enclosure is

necessary, Model EPSC may be placed adjacent to walls of

combustible construction at the minimum clearance specied

on each pipe section and in the individual Listing; see

CLEARANCES section and Table 1-1. Contact local building

or re ofcials about restrictions and installation inspection

requirements in your area.

MAX. FREESTANDING ABOVE ROOF SUPPORT

ft (m)

Table 1-5: Freestanding Above Roof Support

Proper guying and bracing is essential for part of the vent

that extends above the roof or parapet wall. The vent at

this point is subject to wind conditions and needs special

attention for proper stabilization.

If the vent above the roof does not exceed dimensions in

Table 1-5, no special guying or bracing is required. However,

to protect the ashing from lateral movement, a guide

must be installed at the roof level. The vertical freestanding

height above the roof or top guide is limited due to wind

considerations.

For vent height above the roof that needs guying or bracing,

a support, a small length and a expansion length must be

installed near the roof level to absorb the thermal expansion

and minimize this effect on the guy wire or brace.

When using guy wire, the cable must be slightly slack or

loose to allow thermal expansion.

1.13 HORIZONTAL/VERTICAL GUIDE SPACING

Full Rings are used in vertical installations as wall guides to

maintain proper alignment of the system and are for lateral

support for wind loads.

steel (provided by others). See Table 1-7 for maximum

spacing between horizontal supports.

Plate Supports are also used to support and stabilize the

system at changes in direction and when using expansion

sections.

1.15 VERTICAL INSTALLATION REQUIREMENTS

Vent systems without provisions for draining rain water must

use a Rain Cap.

Terminations or approved mechanical draft systems specied

or provided by the appliance manufacturer are permitted.

010.8030.1222 12.22

collar. A condensate drain is also required for every 30 feet of

horizontal vent and at the bottom of a vertical stack.

Use the Drain length for a straight horizontal run. Rotate the

tting so that the drain tube is as vertical as possible.

Use a Tee at a transition from horizontal to vertical, and attach

the Drain Tee Cap to the appropriate branch of the tee.

Flue gas condensate can have a low (3 to 5) PH level, follow

all local and national codes and regulations for the draining of

acidic condensate.

The total continuous distance of the vent system from the

appliance ue collar to the termination shall not exceed

that specied in the appliance manufacturer’s installation

instructions.

In general, systems installed in cold climates perform

best,and condensation is reduced, when the system is fully

enclosed by some part of the building structure or by using

insulated EPS1 venting system.

Condensate drains should not be installed on the exterior of

the building. Doing so may result in dangerous icy conditions

on surfaces near the drain and may cause damage to the

vent system and/or the building exterior. or property damage

due to any formation of ice.

Vertical supports are required after every transition to vertical.

Vertical supports are also required after every offset elbow.

Unless the EPSC is installed in a re rated shaft, a roof

thimble and support is required when penetrating re rated

oors, walls or ceilings.

1.16 WALL PENETRATION

Prior to installation, determine proper location of wall thimble

so that a minimum slope of 1/4” (6mm) per foot is maintained

in the horizontal section of vent to ensure proper ow of

condensation.

Prepare the wall by cutting a square opening.

Apply a bead of sealant around the edges of the exterior

(smaller of the two parts) wall thimble component. Then

install this part of the wall thimble by inserting the smaller

collar into the other component from the previous step.

NOTE: The two horizontal cylinders of the thimble must

engage a minimum of two inches.

Fasten both sides of the wall thimble using screws.

Once the thimble is installed, EPSC vent pipe can be inserted

into the thimble.

Close the gap between the thimble and the vent by installing

the two half plate and fasten it using screws.

Install horizontal termination to complete the assembly.

Once assembly is completed, apply a bead of high-temp

sealant around the pipe and the exterior two half plates of the

thimble to protect against weather.

The air gap can be lled with eld installed insulation

when using the insulated wall thimble depending upon

the adopted code, seismic zone, duct size, location

in building, etc. and are not within the scope of these

installation instructions.

1.17 CONDENSATION DRAINS

When an internal condensate drain is NOT part of the

appliance, a Drain length or a Tee with a Drain Tee Cap is

strongly recommended.

Install this drain as close as possible to the appliance ue

010.8030.1222 12.22

Do not secure screws into the vent. The lock-

ing band is the only thing needed for proper

assembly.

Risk of injury. Sheet metal parts may be

sharp. Always wear gloves and appropriate

eye, foot, and other protection when handling

these products.

1.18 VENT JOINT ASSEMBLY

All EPSC components feature a simple push-t joint design,

allowing ease and speed of installation, while maintaining a

secure and pressure tight joint. To assemble the joint, simply

follow the steps below.

1. EPSC are always installed with the female spigot facing

towards the termination and the male end facing

towards the appliance. The product label includes an

arrow pointing away from the appliance. See Fig. 1-1

2. Having checked the correct orientation of the product,

clean both the male and female ends with a suitable cloth

to ensure they are free from dirt and grit.

3. Apply a generous amount of RTV Silicone around the

outer circumference of the male end. Do the same around

the inner circumference of the Elastomer Seal, while also

checking the seal for any potential signs of damage. See

Fig. 1-2.

4. After applying RTV Silicone, align the male end into the

female and push the joint together using a slight twisting

action.

5. With the joint assembled, locate the Locking Band around

the joint as detailed in Fig. 1-3. The Locking Band must be

installed so that the toggle is only closed from left to right.

NOTE: Hi Temp RTV Silicone with a temperature up to 500°F

is suggested to provide additional sealing.

1.19 LOCKING BAND ASSEMBLY

The locking band has a unique prole and must be installed

using the correct orientation. It MUST be located so the snap

lock is only closed from left to right.

1. Attach the drawer to the latch See Fig. 1-4

2. Pull the drawer handle to the left to lock in place. See

Fig. 1-5.

1.20 REPLACING A SEAL

The Elastomer Seal offers many years of troublefree service.

However, improper installation or assembly of the vent can

potentially damage the seal which can cause leakage.

Follow these steps to replace a seal:

1. Remove the old seal and fully clean the location groove for

residue.

2. Apply a thin bead of silicone sealant around the internal

circumference of the seal groove making sure there

is enough to bond the seal to the vent.

3. Position the new seal in the groove and make sure the

vanes of the seal are facing down toward the male end.

4. Once in place, make sure the seal is rmly located back

against the rear end of the seal groove. Make sure there

is no silicone residue on the vanes which can impact the

pressure and condensate resistance of the joint. Allow 24

hours to cure before installing.
