Installation, service, commissioning and annual 
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 door secured by 4 
sheet metal screws. Opening the door exposes live 
electrical connections and hot components.

Ensure that the heater and all controls are suitable 
for the gas, pressure and electrical supply to which 
they are to be connected.

Where fitted, the air delivery louvres need to be set 
during commissioning to give the required air 
distribution (optional vertical louvres).

All pre-commission checks must be carried out 
before commissioning the heater.

1. Check that all site wiring is connected in 

accordance with the appropriate wiring diagram 
on Page 14, Section 9.3.

2. Check the correct fuse size is fitted;

See Page 13, Section 9.1.

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.
Ensure that the air is fully purged from the heater 
inlet pipe up to the main gas valve inlet test nipple.
10.1.4 Mechanical Checks

1. Check that the fan is free to run and 

delivery louvres are turned to give required air 
deflection.

2. Check that the flue (and air intake for room 

sealed) is installed in accordance with these 
instructions and local regulations.

 The limit thermostat is sealed at the factory 

and is not adjustable.

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 16, Figure 9.

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