6. Installation

6.1 Installation Overview

The installation of your new Unit Heater requires a few easy-to-follow steps.

These steps are described below. You will need to gather the required tools,

choose a suitable area for locating the heater, install either hanging mounts or

a floor support mount for the heater, install the flue system and flue pipe,

connect the gas supply, install the power cord and thermostat to the heater

control box, and test the heater.

This manual provides a general description of the flue pipe installation in

Section 6.5. It is recommended that the flue be installed by a trained

experienced service technician. The heater mounting requires advanced

planning. For example, if a mounting frame or support is required, this will

need to be constructed and installed in advance. It is recommended that

electrical outlets be installed by a certified electrician.

6.2 Tools Required

Adjustable Wrench

Hammer or Drill to Install Screw Hooks in Ceiling

¼” Nut Driver

Pipe Glue

Gas Leak Testing Solution (A soap and water solution works well).

6.3 Receiving and Unpacking

Your heater is shipped completely assembled except for the power cord and

thermostat which you will have to attach to the control box. Unpack the

heater and check for any shipping damage. If you suspect shipping damage,

contact your local Distributor.

6.4 Hanging Or Floor Mounting

In order to ensure proper ventilation and safety, the heater requires minimum

clearances of 6 inches from each side of the heater, a minimum of 6 inches

from the top of the heater, 18 inches from the back of the heater, and requires

6 inches from the flue pipe to adjacent surfaces. The heater must be

positioned so as to prevent contact within 10 feet of the hot air discharge from

the front of the heater. Choose a location of the heater which isolates heater

from accidental drafts and permits installation of a flue pipe (See Section 6.5;

See Section 1.2 Ventilation Requirements, page 1).

6.4.1 Hanging The Heater

Model 100 and Model 200 are designed to be suspended from the Top only.

Model 300 can be suspended from either the Top or the Bottom, as desired.

To prepare the heater for hanging, you will have to install threaded hooks,

eyebolts, or rods into the mounting holes of the heater. Locate the mounting

Part No. 4801-2987 Unit Heater 6

holes designed for receiving the hooks or rods. These hole locations are

labeled as H, I, and J in Section 5.1, page 4. For Model 300, there are ten

holes on the Top and ten holes on the Bottom which may be used to hang the

heater. The thread size of the mounting holes is 1/4-20.

The method of supporting the heater is the installer’s choice and

responsibility. Install the desired suspension supports into the ceiling. Make

sure that the ceiling supports are adequate to support the weight of the

heater. Screw the mounting holes of the heater appropriately threaded rods,

hooks, or eyebolts being used to attach cables or chains. Lift the heater into

position and suspend the heater on the previously installed ceiling supports.

Make sure to allow the required separation distances between the heater and

the ceiling and walls as described above and in Table 1.

6.4.2 Floor Mounting The Heater

If the heater is mounted on a floor stand, make sure that the stand has

sufficient strength to support the heater. Make sure that the heater is

securely attached to the stand, and that the heater and stand are not top-

heavy or unstable. It is recommended to secure a floor stand to the floor with

bolts. Be sure to construct the floor stand from non-combustible materials.

6.5 Flue Pipe Installation

Unit heaters must be vented in compliance with local codes, and within

standards of the American National Flue Gas Code, ANSI Z-223.1 or Canada

CAN/CGA-B149 installation codes. Flue gases are exhausted through the

exhaust blower on the rear of the heater, and must be vented to the outside of

the building through a flue system. The flue system is the responsibility of the

installer. It is recommended that the flue pipe be installed by an authorized

heater representative.

6.5.1 Flue Connector And Size Adapter

The exhaust blower must be coupled to the flue by attaching a flue connector

which is included with your heater. Attach the flue connector to the exhaust

blower as shown in Figure 1, page 7. Secure the flue connector with non-

corrosive screws. The flue connector output has a 4” diameter. A size

adapter must be attached to change diameters of the flue pipe. The size

adapter is not supplied with the heater. The size adapter is a metal vent pipe

which transitions from a 4” diameter to 5” diameter for Model 100, 6” diameter

for Model 200, or 7” diameter for Model 300. After attaching the flue

connector and size adapter, all seams and joints must be sealed with high

temperature jointing compound or jointing material such as aluminum tape.

Aluminum tape must meet the SMACNA AFTS-100-73 Standards. Silicone

rubber sealant must have a temperature rating of at least 400 degrees

Fahrenheit. All joints must be checked for tightness of fit after installation.

Part No. 4801-2987 Unit Heater 7

6.5.2 Flue Pipe

Refer to Figure 2, page 8. The flue is composed of short sections and elbows

of metal vent pipe joined together to connect the heater to the flue terminator

which extends to the outside of the building. The flue diameter is 4” for

Model 100, 5” diameter for Model 200, or 6” diameter for Model 300. All joints

and seams of the flue pipe must be sealed with high temperature silicon

rubber sealant or aluminum tape. The flue should be as short as possible

and have a minimum number of elbows. All joints must be secured by at

least two screws. After installation of the flue, check all joints for tightness.

Refer to National Standards NFPA 54/ANSI Z223.1 for U.S.A. or Canada

Standard CAN/CGA B149.1 and B149.2. If using a high temperature plastic

flue pipe (instead of metal), the first 18 inches of pipe extending from the flue

connector must be metal to prevent heat damage. The horizontally running

sections of the flue must normally maintain a slope of 1/4” rise per each foot

of horizontal run of the flue. The flue pipe should be supported with hangers

no more than 3 feet apart to prevent movement. Install a condenser tee and

drain within the first 5 feet of the heater. If a fume trap is used, be sure to

keep it filled with water.

The flue pipe must be 6 feet or more from an inside corner formed by two

exterior walls. If a single wall flue is used in an unheated area it should be

insulated with fiberglass to prevent excess condensation of flue gases.

If the flue pipe passes through a combustible wall, an insulating thimble

should be used (See Figure 2, page 8).

After passing through an outside wall, the flue pipe should be turned vertically

using an elbow. The vertically running segment of the flue pipe should be at

least 12 inches from the outside wall. The outside segment of the flue pipe

should extend vertically to at least 3 feet above the highest point of the roof

and should be terminated with a flue cowl.
