3. Burner must be cleaned
4. Orifice must be cleaned
5. Gas supply tube from thermostat to burner must be cleaned
6. Chimney & Boiler tube must be clean of debris
7. Deflector/Strangler must be clean of debris
8. Filter in Thermostat Gas control needs to be cleaned or replaced
9. Adequate ventilation around fridge
10. Thermocouple connections to be snug, not over tightened
To reduce problems during summer season, (i.e.. weekend use), it is best to leave the fridge running on low
setting during the week. If shut down on a Sunday, spiders may seek the propane odor (mercaptin), and
create a restriction of the gas flow. This in turn will reduce/stop the operational efficiency of your absorption
fridge/freezers.
Note: Installation and service must be by licensed gas fitter in accordance with local
codes or must comply with Propane Installation Code.

The importance of leveling the fridge is to ensure that the
solutions in the absorption unit flow freely and mix correctly.
Without proper leveling, you will not achieve adequate cooling
inside the fridge, and/or cause damage to the system.

A dirty burner will create carbon build-up, along with
carbon monoxide gases. It will also cause low heat to
be produced from the flame, which in turn will cause
poor cooling.

Each time the fridge is serviced, the burner must be cleaned.
Use a small brush to clean out the burner tube to free it of any
spider webs, use a wire brush to clean any build up that has
clogged the screen, and finish by blowing it out with
compressed air.
