SECTION 2: INSTALLER

RESPONSIBILITY

The installer is responsible for the following:

• To install the heater, as well as the gas and

electrical supplies, in accordance with applicable

speciﬁcations and codes. Big Ass Fans

recommends the installer contact a local Building

Inspector or Fire Marshal for guidance.

• To use the information given in a layout drawing

and in the manual together with the cited codes

and regulations to perform the installation.

• To install the heater in accordance with the

clearances to combustibles.

• To furnish all needed materials not furnished as

standard equipment.

• To plan location of supports.

• To provide access on all sides for burner servicing

and removal.

• To provide the owner with a copy of this

Installation, Operation, and Service Manual.

• To never use heater as a support for a ladder

or other access equipment and never hang or

suspend anything from heater.

• To ensure there is adequate air circulation around

the heater and to supply air for combustion,

ventilation, and distribution in accordance with

local codes.

• To safely and adequately install heater using

materials with a minimal working load of 75 lb

(33kg).

• To ensure the heater is placed in an approved

application.

2.1 Wall Tag

A wall tag is available for the heater as a

permanent reminder of the safety instructions

and the importance of the required clearances

to combustibles. Ax the tag to a wall near the

heater. Locate your the model number and install

conﬁguration located on the burner and noted in

this manual. On the tag, write the proper clearance

dimensions in permanent ink according to your

model number and conﬁguration in the open spaces.

Caution

Product Damage Hazard

Do not use heater in area containing corrosive

chemicals.

Refer to appropriate Material Safety Data Sheets

(MSDS).

Failure to follow these instructions can result in

product damage.

Big Ass Fans cannot be responsible for ensuring

that all appropriate safety measures are undertaken

prior to installation; this is entirely the responsibility

of the installer. It is essential that the contractor, the

sub-contractor, or the owner identiﬁes the presence

of combustible materials, corrosive chemicals,

or halogenated hydrocarbons* anywhere in the

premises.

* Halogenated Hydrocarbons are a family of

chemical compounds characterized by the presence

of halogen elements (ﬂuorine, chlorine, bromine,

etc.). These compounds are frequently used in

refrigerants, cleaning agents, solvents, etc. If these

compounds enter the air supply of the burner, the

lifespan of the heater components will be greatly

reduced. An outside air supply must be provided

to the burners whenever the presence of these

compounds is suspected. Warranty will be invalid if

the heater is exposed to halogenated hydrocarbons.

2.3 National Standards and Applicable

Codes

All appliances must be installed in accordance with

the latest revision of the applicable standards and

national codes. This refers also to the electric, gas,

and venting installation. Note: Additional standards

for installations in public garages, aircraft hangars,

etc. may be applicable.

SECTION 3: CLEARANCES TO

COMBUSTIBLES

3.1 Required Clearances to Combustibles

Clearances are the required distances that

combustible objects must be away from the heater

to prevent serious ﬁre hazards. Combustibles are

materials that may catch on ﬁre and include common

items such as wood, paper, rubber, fabric, etc.

Maintain clearances to combustibles at all times for

safety.

Clearances for all heater models are located on the

burner of the heater and on the following pages of

this manual. Check the clearances on each burner

for the model of heater being installed to make sure

the product is suitable for your application and the

clearances are maintained. Read and follow the

safety guidelines below:

• Keep gasoline or other combustible materials

including ﬂammable objects, liquids, dust, or vapors

away from this heater or any other appliance.

• The stated clearances to combustibles represents

a surface temperature of 90 °F (32 °C) above room

temperature. Building materials with a low heat

tolerance (such as plastics, vinyl siding, canvas,

tri-ply, etc.) may be subject to degradation at lower

temperatures. It is the installer’s responsibility to

assure that adjacent materials are protected from

degradation.

• Maintain clearances from heat-sensitive equipment

and workstations.

• Maintain clearances from vehicles parked below

the heater.

• Maintain clearances from swinging and overhead

doors, overhead cranes, vehicle lifts, partitions,

storage racks, hoists, building construction, etc.

• In locations used for the storage of combustible

materials, signs must be posted to specify the

maximum permissible stacking height to maintain

required clearances from the heater to the

combustibles. Signs must be posted adjacent to the

heater thermostat. In the absence of a thermostat,

signs must be posted in a conspicuous location.

• Consult local Fire Marshal, Fire Insurance Carrier,

or other authorities for approval of proposed

installation when there is a possibility of exposure

to combustible airborne materials or vapors.

• Hang heater in accordance to the minimum

suspension requirements shown in “FIGURE 11:

Critical Hanger Placement” on page 13.

Warning

Fire Hazard

Keep all ﬂammable objects, liquids, and vapors

the minimum required clearances to combustibles

away from heater.

Some objects will catch ﬁre or explode when placed

close to heater.

Failure to follow these instructions can result in

death, injury, or property damage.

• If the radiant tubes must pass through the building

structure, ensure that adequate sleeving and ﬁre

stop is installed to prevent scorching and/or ﬁre

hazard.

NOTE

1. All dimensions are from the surfaces of all tubes and couplings.

2.Clearances B, C, and D can be reduced by 50% after 25 ft (7.5 m) of tubing downstream from where the burner

and burner tube connect.
