After commissioning, the heater will require 
maintenance to be carried out annually. If the heater 
is used in a dirty or dusty area, more frequent 
maintenance may be necessary.

Installation, service and annual inspection of 

heater must be done by a contractor qualified

in the installation and service of gas-fired heating 
equipment.

NOTE 1: After any maintenance or repair work 
always test fire the heater in accordance with the 
commissioning instructions 

through Page 24, Section 11.9 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 

Section 15 through Page 35, Section 15.5.

NOTE 2: 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.

NOTE 3: Inspect all suspended components and 
hardware. Insure that they are in good condition, 
properly tightened, and corrosion free.

1. Open the hinged door and remove the burner 

compartment cover. 

See Page 37, Section 16.2.

2. Clean any deposits from the main burner which 

may have formed in the injectors or venturi of 
the burner. 

See Page 37, Section 16.2.

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 necessary.

The main fan bearings are permanently sealed and 
do not need lubrication. Before cleaning, turn off gas 
and electrical supply. Remove the fan(s) and use a 
small brush or duster to clean the fan blades from 
each side. Replace fan(s) when done.

The heat exchanger will remain clean unless a 
problem has developed with combustion. Inspect the
