SECTION 13: SERVICING
13.1 Servicing Instructions
After start-up, the heater will require maintenance to 
be carried out, at a minimum, annually. If the heater 
is used in a dirty or dusty area, more frequent 
maintenance may be required.
IMPORTANT: After any maintenance or repair work, 
always test fire the heater in accordance with the 
start-up instructions 
on Page 26, Section 11 through 
Page 28, Section 11.3.1 to ensure all safety systems 
are in working order before leaving the heater to 
operate. Minor faults may be traced by using the 
troubleshooting charts 
on Page 34, Section 14 
through Page 38, Section 14.5.
IMPORTANT: Check all gas pipes and pipe joints to 
ensure there are no cracks or gas leaks. Any cracks 
in the pipes or pipe joints must be repaired.
IMPORTANT: Inspect all suspended components 
and hardware. Ensure that they are in good 
condition, properly tightened, and corrosion free.
13.2 Burner Maintenance
1. Open the door and remove the burner 
compartment cover. 
See Page 40, Section 
15.2.
2. Clean any deposits from the main burner which 
may have formed in the injectors or venturi of 
the burner. 
See Page 40, Section 15.2.1.
3. Remove the ignition electrode and flame probe. 
Check condition of ignition electrode and flame 
probe. Clean off any deposits which may have 
been formed, check condition of ceramic 
insulators. Replace as required. 
See Page 41, 
Figure 15.3.
13.3 Heat Exchanger Maintenance
The heat exchanger will remain clean unless a 
problem has developed with combustion. Inspect the 
heat exchanger. Look for signs of overheating at the 
front tubes which may indicate burner over firing or 
persistently low air flows.
13.4 Gas Valve Maintenance
No regular maintenance is required on this device. 
To change gas control valves, 
See Page 39, Section 
15.1.
Do not repair or disassemble gas valve.
Replace faulty gas valves with replacement parts 
sold and supplied by Roberts-Gordon LLC.
13.5 Flue Blower
The flue blower should not require maintenance. 
However, if the air pressure switch is causing burner 
lockout, then remove the flue blower from the vent 
box by unscrewing the three screws at the mounting 
plate. Remove the four screws attaching the 
mounting plate to the fan inlet (
See Page 42, 
Section 15.5). Ensure that the fan is free to run and 
that the fan wheel is clean.
13.6 Venting and Air Intake Pipe
Inspect all venting and air intake pipe. Ensure that 
all seams are sealed and suspension points secure. 
Repair suspension points if any part of the venting 
or combustion air pipe is sagging. Check to make 
sure any insulation is not missing or in poor 
condition. Replace as required. Check all venting 
and air intake components to ensure they are in 
good condition, gas tight and corrosion-free.

during installation, 
operation and service.
Edges are sharp.
