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.

Series GR Page 8 February 10, 2014
Installation Detail
Installation Sequence
The heater is sent with all parts necessary for installation with the exception of chain.
It is recommended that the heater be hung as high as possible and along an uncluttered wall to give the
reflector a widest possible “view” of the space to be heated. Avoid installation directly over vehicle
parking, over cabinets, or where an open door will interfere. Adhere to minimum clearances on the rating
plate.
Leave adequate space around the burner box for future servicing.
Choose a location that permits easy installation of exterior venting. A horizontal vent length up to 10' feet
is allowed. For vertical venting adhere to local venting tables and methods.

Note:
Close all open ended "S" hooks, chain links,
and turnbuckles or any open connection.
Figure 3: General Overview of Components Utilized in the Installation
As required, fasten hanging angles to ceiling such that heater-hanging points can be accommodated.
Each hanging point must be able to hold at least 150 lbs.
Allow for movement of heater during expansion and contraction during operating cycle.
Heater must fire horizontally. To tilt reflector at 45°, lengthen two of the hanging points to an appropriate
length using chain. (Each chain length will be approximately 12" inches longer than the high side of the
heater). SRP recommends and make available “quick links” for connecting chain. If any open
ended “S” hooks and turnbuckles are used, the open ends must be closed to avoid unhooking chain
with inadvertent contact.
Series GR Page 9 February 10, 2014
Installation Detail
Outdoor Installation
For outdoor installations the heater must be installed not more than 8" from beneath awnings, and not
less than 24" from back and side as shown in Figure 4. If the heater cannot be protected from the
elements by an overhang, then a protective cover must be installed as shown in Figure 7, Figure 8 and
Figure 9.
Note:
Close all open ended "S" hooks, chain links,
and turnbuckles or any open connectio n.

8"
24"
BACK
When the heater is installed with back and side dimensions greater than the minimum of 24" then
the top dimension may be increased. The new maximum Top dimension is 1/3 of the smallest side or
back clearance.
Example:
Given: Side dimension = 36"
Back dimension = 48"
A ratio of 3:1 must be maintained
The side dimension gives us a maximum Top dimension of (36/3)" = 12"
The back dimension gives us a maximum Top dimension of (48/3)" = 16"
The new Top dimension is 12", the lesser of the two.

P/N RS006
A flue/air vent length of 8 feet or less is recommended, although a maximum of 10' feet is
allowable (including one elbow).
An approved Wall Terminal that allows the air duct to pass through the wall is required. This is
included with your heater. The Wall Terminal is a zero clearance terminal for both combustible
and non-combustible walls.
For horizontal venting where an elbow is utilized an elbow kit (Part No. RT013) must be used,
refer to Figure 10 for more details.
The 2" inch flue pipe should extend a minimum of 6" inches beyond the end of the 4" inch wall terminal
(for horizontally vented heaters only see Figure 12). Where the vent is under an eave the 2" vent pipe
must have a minimum clearance of 7" from the centerline of the vent to the bottom of the eave, refer to
Figure 11. However, when the 2" pipe is less than 18" from the bottom of the eave, we
recommend the 2" inch flue extend just beyond the eave to prevent the possibility of frost. (Adhere
to any code requirements for clearances to opening in the building).
An optional “Horizontal Elbow Vent Terminal” kit for horizontal venting is also available, refer to

Gas Piping
General Requirements
The gas meter and service must be sufficiently large to supply gas to the connected building gas
load including the heating equipment and any other gas-fired equipment. Additionally, the gas
distribution piping must be designed according to local and national ordinances. Generally (low
pressure) systems designed with a maximum 1/2"-inch W.C. total pressure drop meet this
requirement.
Gas supply pipe sizing must be in accordance with 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.
Before connecting burners to the gas supply system, verify that high pressure testing of the system
has been completed. Failure to do so may expose the burner components to damaging high
pressure, requiring replacement of key components.
Flexible gas connectors of approved type must be installed as shown in Figure 15, in one plane,
and without sharp bends, kinks or twists. A smooth loop of approximately 12" inches in diameter
is best. Failure to install the gas connection in the approved manner will result in a hazardous and
potentially deadly situation due to the movement of the heat exchanger and burner in the normal
course of operation.

Electrical Wiring
General Requirements
Heaters are normally controlled with the thermostat that is included with your equipment. A 24V signal is
supplied by the heater control module for thermostat connection. Refer to wiring diagram, Figure 16. A
bulkhead fitting in the back panel of the control box is provided for the appropriate wire. In all cases,
heaters must be 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.
If any of the original wire as supplied with the heater must be replaced, it must be replaced with wiring
having a rating of at least 105°C temperature service and 600 volts capability.

Operation / Maintenance
Starting Sequence of Operation
Turn the thermostat up. When the thermostat calls for heat, the blower motor will energize.
When the motor approaches nominal running RPM, the air-proving switch closes and activates the
ignition module.
The ignition module, after a pre-purge period of approximately 30 seconds, energizes the igniter.
Additionally, the gas valve is energized for this ignition trial period of 15 seconds.
If a flame is detected, the ignition sensing rod "reads" a rectification signal and the gas valve
remains open. The sparking stops when the flame signal is established.
If no flame is detected, the gas valve closes and a 30 sec inter-purge period begins. After the inter-
purge, the module repeats the trial for ignition period. If flame is still not established, a third and
final inter-purge followed by a final ignition trial cycle begins. After three trials, the module will
lockout for a period of approximately 1 hour or until reset. (Reset is accomplished by removing
power from the module for at least 5 seconds.) After this 1-hour period, the module re-attempts the
full ignition sequence.
When using a 24V thermostat and the heat requirement has been met and the thermostat opens, the
burner shuts off but the fan continues to run for approximately 30 seconds. This is referred to as a
post purge. This allows the products of combustion to be removed from the heat exchanger to avoid
nuisance condensation and increase heat exchanger life.
When using a line voltage thermostat and the heat requirement has been met and the thermostat
opens, the burner and fan shut off with no post purge.
Maintenance
For best performance, the following minimal maintenance procedures should be performed before each
heating season:
Before performing any service or maintenance, shut off gas and electrical supply to heater.
Check condition of forced air blower scroll and motor. Dirt and dust may be blown or vacuumed
from the blower.
Check condition of burner. Remove any foreign objects or debris from inside the burner box or
burner cup.
Inspect the igniter. Replace igniter if there is excessive wear or erosion, breakage or other defects.
Check inside the heat exchanger tube visually with a flashlight. If carbon or scale are present,
scrape or otherwise remove deposits (a wire brush works well).
Be sure the burner observation window is clean and free of cracks or holes. Clean or replace as
necessary.
Check the flue pipe for soot or dirt and reattach to the heater after cleaning as necessary.
The heat exchanger reflector sections may be cleaned by wiping with a damp cloth.
A service agency qualified to adjust and repair infrared heaters should be engaged for service
other than routine maintenance.
Be sure vent terminal and fresh air inlet are free f rom obstructions. If either pipe is restricted, the
safety air switch will not operate properly, and the heater could fail to operate.
Series GR Page 20 February 10, 2014
Trouble Shooting
Blower Motor Fails to Run
Is the thermostat calling for heat? Is there 115V at the burner receptacle?
Check blower side door for seal. Repair as necessary.
Check blower for obstructions. Replace blower if necessary.
No Gas Supply
Check to see if manual supply valve to heater is ON.
Check to see if gas valve knob on heater gas control is ON.
Supply gas pressure can be checked at 1/8" NPT pressure tapping in gas supply system.
Is combination gas control opening? No manifold pressure indicates valve is closed. Gas pressure
downstream of gas control can be measured by connecting a manometer to pressure tap on control.
If the valve is closed, either the gas valve or the ignition module is faulty.
Burner Does Not Light
Is spark visible through site glass during ignition trial? If no, further electrical checks by a
qualified service person are probably necessary.
Check to see if gas lines were properly purged of air.
Check inlet and outlet gas pressure during ignition period.
Check for orifice and air plate obstruction.
Burner Does Not Stay Lit
Check ground wire continuity.
Check insulation on the igniter leads.
Measure flame signal current; it should be above 0.8 micro amps DC.
Replace module if necessary.
