COMMISSIONING
COMMISSIONING TESTS & ADJUSTMENT PROCEDURES
GAS INLET PRESSURE TEST
IMPORTANT –
Check the gas supply pressure at the gas inlet to the heater with all other gas burning appliances in
the premises operating (burners alight). The minimum gas supply pressures are:
•
Natural Gas: 1.13 kPa
•
Propane: 2.75 kPa
If this minimum cannot be achieved, it may indicate the meter or the gas line to the heater is undersized. It is
important to ensure that an adequate gas supply pressure is available to the heater when all gas burning appliances
on the same gas supply are operating.
The maximum gas pressure must NOT exceed 3.5 kPa.
SETTING HEATER FLUE TYPE
The controller must be set according to the heater flue type at time of commissioning. Combustion fan speed is
automatically adjusted according to the flue type setting to aid combustion.
