o
From the heater, ensure there is a gradual fall/ decline
with no rises
o
Air Intake flue:
▪
Obstructions/ blockages
▪
Torn, ripped, crushed or dislodged
o
Flue Checks:
▪
Obstructions/ blockages
▪
Water Build up (Condensate)
▪
Tight pipe bend radius
•
Listen for solenoid opening. Should be a click noise
See page 10 Electronic/ component related issues for detail of
ignition cycle
•
Listen for ticking sound from Spark generator
4.1.1.2 – 2 Bars: Overheat
Process
•
Wait 5-10mins before trying to clear the lockout (see 4.1.1). This is
to allow the overheat stat to reset.
•
Check for any obstructed inlets or outlets.
•
Are there any fixed / open outlets in the ducting system?
Minimum of 1 open is required.
•
Electric element issues:
o
Resistance check
o
Relays check
•
Check temperature sensor
•
Check over-heat stat – should be normally closed circuit
4.1.1.3 – 3 Bars: Low/High supply voltage
Process
•
Try to clear lockout (see 4.1.1)
•
Check battery voltage on Control Panel and supply at the Heater
•
Check battery terminals are tight and have a sound connection
•
Check output from PSU and the wire gauge is correct
•
Have either a generator/ motor mover been in use?
•
Where two batteries are fitted, ensure they are correctly wired in
parallel, not in series as this will increase the voltage
•
Solar panel - check supplies to the system from the charge
controller/ switch. Ensure no more than 15 volts is supplied during
periods of high levels of sunshine
•
Panel may need to be removed from system to check Heater

Try to operate the Heater again on gas
after the flue is re-assembled.
If not heard, then replace solenoid coil
– Service Engineer only.
If not heard, replace PCB
Actions
This should cure most simple
problems.
Open all vents, check for any
objects in or in front of the vents,
crushed ducting etc.
If elements fail resistance
check/current draw replace
elements (Service Engineer only).
Should
the
elements
remain
energised from the PCB, the relays
on the PCB are faulty. The PCB
requires replacement.
Check cables have continuity. If
damaged, re-crimp or replace.
Actions
This should cure most simple
problems.
If the voltage is below or around
10.4V charge the battery.
If the voltage is above 14.5V then
there is a power supply issue.
Check alternator/ external battery
charging/ solar over charge.
