Cleaning Fuel Lines
Any blockage in the fuel line from the oil-metering valve to the burner can be cleaned by
removing the clean-out plug situated directly under the burner. The plug must be replaced
with tape sealant and checked for leaks. The fuel lines themselves can be cleaned with
compressed air or a pipe cleaner to remove any blockages. Tap the fuel line to relieve air
locks.
Cleaning Combustion Chamber
This is the cemented area above the burner where the flame burns. The cement will show hair
line cracks immediately on firing the heater. These cracks will not affect the burning of the heater.
Re-lining the combustion chamber will only become necessary if the cement becomes loose or
detached.

CEMENT REPLACEMENT INSTRUCTIONS
1. Chip away all old cement from the heater. Then mix the new insoline cement powder
with water. It is not too important to get the consistency exact but oatmeal is a good
consistency to aim for.
2. Paste the new cement in with a trowel or a wide knife. The cement will need 24 hours
to dry completely.
3. Use any left over cement to repair any cracks in the insoline cement as the combustion
chamber needs to be air tight for the heater to work correctly.
4. Allow 24 hrs to dry.
