CLEARANCE TO COMBUSTIBLES
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.
appropriate markings adjacent to the thermostat or in a conspicuous location.
Table 2 lists the minimum clearance to combustible materials for various installation congurations. Note
that standard clearances also apply to installation above T-bar ceilings and above decorative grills. Additional
clearance may be required for glass, painted surfaces and other materials which maybe damaged by radiant or
convective heat.
Combustible materials are considered to be wood, compressed paper, plant bers, plastics, Plexiglas or other
materials capable of being ignited and burned. Such materials shall be considered combustible even though
ameproofed, re-retardant treated or plastered.
Reector miter kits are available for U-bends and elbows.
Adequate clearance to sprinkler heads must be maintained (NFPA 13: Standard for the Installation of Sprinkler
Systems).
The stated clearance to combustibles represents a surface temperature of 90°F (32°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 identied with signs or appropriate markings.

Figure 2: General Overview of Components Utilized in the Installation
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 reector
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.
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 re horizontally. To tilt reector 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. “Quick
hooks and turnbuckles are used, the open ends must be closed to avoid unhooking chain with inadvertent
contact.

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.
When the heater is installed with back and side dimensions greater than the minimum of 24” then the
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.

•A ue/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 Thimble 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 9 for more details.
•The 2" inch ue pipe should extend a minimum of 6" inches beyond the end of the 4" inch wall terminal (for
horizontally vented heaters only see Figure 11). 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 10. However, when the 2" pipe is less than 18" from the bottom of the eave, we recommend the 2"
inch ue extend just beyond the eave to prevent the possibility of frost. (Adhere to any code requirements
for clearances to opening in the building).
•The 2”-inch ue vent is inside (concentric with) the 4” inch combustion air inlet duct. Each of the
former must be seamless and all joints must be fastened with screws and sealed with GE RTV-106 high
temperature sealant (or equivalent) refer to Figure 11. The exposed 4” combustion air intake pipe is zero
clearance throughout its length.

GAS PIPING
•The gas meter and service must be sufciently large to supply gas to the connected building gas load
including the heating equipment and any other gas red equipment. Additionally, the gas distribution
piping must be designed according to local and national ordinances. Generally (low pressure) systems
designed with a maximum ½ in 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 US and CSA 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 30, in one plane, and
without sharp bends, kinks or twists. A smooth loop of approximately 12 in (30 cm) 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.

OPERATION AND 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 ame is detected, the ignition sensing rod “reads” a rectication signal and the gas valve remains
open. The sparking stops when the ame signal is established.
••If no ame 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 ame is still not established, a third and nal inter-purge
followed by a nal 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 ashlight. 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 ue pipe for soot or dirt and reattach to the heater after cleaning as necessary.
••The heat exchanger reector sections may be cleaned by wiping with a damp cloth.
••A service agency qualied 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 from obstructions. If either pipe is restricted, the safety air
switch will not operate properly, and the heater could fail to operate.
Page 16Residential Range RS_10062016al
TROUBLESHOOTING
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 if 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 qualied 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 orice and air plate obstruction.
Burner Does Not Stay Lit
•Check ground wire continuity.
•Check insulation on the igniter leads.
•Measure ame signal current; it should be above 0.8 micro amps DC.
•Replace module if necessary.
