MAINTENANCE & SERVICE
Maintenance and servicing must be done by a qualified burner technician or shortened furnace life and
poor efficiency may result. Under Tests and Observations and Requirements in CSA B139, the installer is
required to perform tests to ensure proper and safe operating conditions. Newmac requires the installer to
fill out the
INSTALLER INFORMATION
sheet found in this manual.
CLEANING
The heat exchanger should be inspected on an annual basis. If cleaning is required, remove the cleanout
cover. Use a wire brush or cleaning tool (available from Newmac) to loosen scale and soot and a vacuum
cleaner to remove it from the furnace. Replace gaskets if necessary before replacing the cleanout cover.
A layer of soot on the heat exchanger surfaces and firetube walls will reduce heat transfer and can
increase fuel consumption significantly. A 1/32” layer of soot acts as an insulator and can result in a 3%
increase in the amount of oil burned. A 1/16” layer may result in an average fuel loss of 8%.
When removing the burner, cleanout or cover panels take care not to damage gaskets.
NH3 FURNACE
- take care not to break the combustion chamber. Removal of the combustion chamber
plate assembly allows a more thorough inspection and cleaning.
Replace all parts properly before starting the appliance.
