inspection of the heater must be done by a 
contractor qualified in the installation and service of 
gas-fired heating equipment. Read this manual 
carefully before installation, commissioning, 
operation, or service of this equipment. All 
components are accessed via the hinged door. 
Opening the door exposes live electrical 
connections and hot components.
Cooling Coils/Condensers

inspection of the cooling equipment must be done 
by a contractor qualified in the installation and 
service of refrigeration equipment. Read condenser 
manufacturer’s manual carefully before installation, 
commissioning, operation, or service of this 
equipment.

11.1 Pre-Commission Checks 
All pre-commission checks must be carried out 
before lighting the heater.
Ensure that the heater and all controls are suitable 
for the gas, pressure and electrical supply to which 
they are to be connected.
11.1.1 Louvres 
Where fitted, the air delivery louvres need to be set 
during commissioning to give the required air 
distribution.

1. Check that all site wiring is connected in 

accordance with the appropriate wiring dia-
grams on Page 17, Section 10.3 through Page 
20, Section 10.6

2. Check the correct fuse size is fitted;

.

11.2 Gas Supply
All aspects of the gas installation including the gas 
meter must be inspected, tested for soundness and 
purged in accordance with local and national codes.

1. Check that the fan is free to run and that the fan 

rotates in the correct direction. To reverse rota-
tion, transpose two of the incoming phase con-
nections.

2. Check that the flue and air intake are installed 

in accordance with these instructions and local 
regulations.

3. Check that the settings of the Combination Fan/

Limit thermostat are correct - See Page 7, Sec-
tion 4.3

NOTE: The second limit thermostat is preset and 
sealed at the factory and is not adjustable.

11.4 Begin Commissioning    
11.4.1 Before Operating the Heater
To ensure that all the controls are in safe working 
order, operate the heater for the first time with the 
isolating gas valve turned off.

1. Turn off the isolating gas valve

2. Using the installed external control, turn on the 

burner. The automatic sequence will now begin 
as described on Page 22, Figure 12.

There will be no ignition of the burner and lockout 
will occur, proving the controls are operating 
correctly.
