CAUTION: FIRE OR EXPLOSION HAZARD
Maintain clearance to combustible constructions as further specified in this manual. Failure
to do so could result in a serious fire hazard. Heaters should not be located in hazardous
atmospheres containing flammable vapors or combustible dusts. Signs should be provided in
storage areas specifying maximum safe stacking height.
CAUTION: MECHANICAL HAZARD
This equipment expands and contracts with each operating cycle. The gas connection,
suspension hardware and the installation itself must safely allow this movement. Failure to
do so could result in serious fire or explosion hazard.
CAUTION: FIRE OR EXPLOSION HAZARD
This heater is equipped with an automatic ignition device. Do not attempt to light the burner
by hand. Failure to comply could result in a serious fire and personal injury hazard.
CAUTION: MECHANICAL HAZARD
Do not use high pressure (above 1/2 psi) to test the gas supply system with the burners
connected. Failure to do so could result in damage to the burner and its control components
requiring replacement.
CAUTION: SERVICE LIFE RISK
Do not install equipment in atmospheres containing halogenated hydrocarbons or other
corrosive chemicals. Failure to do so may lead to premature equipment failure and
invalidation of the warranty. Additionally, it is recommended that the equipment be installed
with a slope downward and away from the burner of ¼" inch in 10' feet to allow start-up
condensate drainage.

Important
These instructions, the layout drawing, local codes and ordinances, and applicable standards such as
apply to gas piping and electrical wiring comprise the basic information needed to complete the
installation, and must be thoroughly understood along with general building codes before proceeding.
Only personnel who have been trained and understand all applicable codes should undertake the
installation. SRP Representatives are Factory Certified in the service and application of this
equipment and can be called on for helpful suggestions about installation.
Installation Codes
Installations must comply with local building codes, or in their absence, the latest edition of the national
regulations and procedures as listed below.
General Installation and Gas Codes
Heaters must be installed only for use with the type of gas appearing on the rating plate, and the
installation must conform to the National Fuel Gas Code, ANSI Z223.1/NFPA 54 in the US and
CAN/CGA B149.1 and B149.2 Installation Codes in Canada.
This heater maybe approved for either indoor or outdoor installation. Not for use in residential dwellings,
refer to Rating plate.
Aircraft Hangar Installation
Installation in aircraft hangars must conform to the Standard for Aircraft Hangars, ANSI/NFPA 409 in the
US and CAN/CGA B149.1 and B149.2 Installation Codes in Canada.
Public Garage Installation
Installation in public garages must conform to the Standard for Parking Structures, NFPA-88A or
Standard for Repair Garages, NFPA 88B, in the US and CAN/CGA B149.1 and B149.2 Installation
Codes in Canada.
Parking Structures
Technical requirements are outlined in ANSI/NFPA 88B (USA)
Series GR Page 4 February 10, 2014
Introduction
The appliance must be isolated from the gas piping system by closing equipment shutoff valve during
any pressure testing of the gas supply piping system at test pressures equal to or less than ½ psi (305
Kpa)
Electrical
All heaters must be electrically grounded in accordance with the National Electric Code, ANSI/NFPA
70 in the USA and the Canadian Electric Code, CSA C22.1 in Canada, and must comply with all local
requirements.
Venting
Refer to the National Fuel Gas Code, ANSI Z223.1 (NFPA 54) in the USA and CAN/CGA B149.1 and
B149.2 Installation Codes in Canada for proper location, sizing and installation of vents as well as
information on clearance requirements for conventional venting methods. See page 11 for horizontal
venting requirements.
This appliance shall not be connected to a chimney flue serving a separate solid-fuel burning
appliance.
High Altitude
When installing this appliance over 4500 ft. above sea level in Canada, the appliance must be properly
de-rated and installed according to local codes. In the absence of local codes the appliance must be derated in accordance with the most recent CAN/CGA-B149 code.
In the United States for installations over 2000ft above sea level the appliance must be installed in
accordance with the Current National Fuel Gas Code, ANSI Z223.1/NFPA 54.
Safety Features
This heater utilizes an airflow switch as blocked vent shut off system. This system is designed to
prevent the operation of the appliance if a fresh air supply is blocked or if the flue exhaust is blocked.
If this system fails to operate DO NOT ATTEMPT ADJUSTMENTS. Disconnect power to the
appliance and contact a qualified service person.

Clearance to Combustibles
Clearance to Combustible Materials.
It is very important to observe the minimum clearance to combustibles at all times to avoid any
possibility of property damage or personal injury.
WARNING
Clearances as marked on the heater body must be maintained from vehicles parked beneath. Signs should
be posted identifying any possible violation of the clearance distances from the heater in all vehicle areas.
Maximum allowable stacking height in storage areas should be identified with signs or appropriate
markings adjacent to the thermostat or in a conspicuous location.
Table 1 lists the minimum clearance to combustible materials for various installation configurations.
Additional clearance may be required for glass, painted surfaces and other materials which may be
damaged by radiant or convective heat.
Combustible materials are considered to be wood, compressed paper, plant fibres, plastics, Plexiglas or
other materials capable of being ignited and burned. Such materials shall be considered combustible
even though flame-proofed, fire-retardant treated or plastered.
The stated clearance to combustibles represents a surface temperature of 90°F (50°C) above room
temperature. Building materials with low heat tolerance (such as plastics, vinyl siding, canvas, tri-ply,
etc…) maybe subject to degradation at lower temperatures. It is the installer’s responsibility to assure
that adjacent materials are protected from degradation.
It is important to observe minimum clearance to combustibles at all times to avoid any possibility of
property damage or personal injury. Clearances must be maintained from vehicles parked beneath heaters.
Signs should be posted identifying any possible violation of the clearance distances from the heater in
vehicle areas. Also maximum allowable stacking height in storage areas should be identified with signs or
appropriate markings. Figure 2 shows minimum clearance to combustible materials.
