Note: The limit thermostat(s) can only be reset
once the unit has cooled down. Unless the
cause of the fault condition is readily obvious,
for example a power cut whilst the heater was
operating, a service engineer should be contacted.
E) Maintenance
To maintain efficient, reliable and safe operation of the
heater it must serviced annually by a qualified person.
F) IMPORTANT
Free access must be maintained to and around the heater
for servicing purposes and the air supply to the heater
must not be restricted in any way. Combustible materials
must not be stored adjacent to the heater.
If at any time a gas leak is suspected, turn OFF the gas
supply at the meter and contact the local gas undertaking
immediately.
All Powrmatic heaters use gas and electricity to power
them, they may also contain moving parts such as pulleys
and belts. It would be hazardous to tamper with or
attempt to service unless you are a competent person in
the field of Gas and Electrical work.
If you have any safety questions reference the servicing
and installation of any of our heaters please do not
hesitate to contact our head office for expert advice. Your
safety is paramount to us.
