COMBINATION FURNACE INSTALLATION
Check with provincial, state or local codes concerning clearances, chimney requirements and other installation
procedures before installation. Some codes may vary from the requirements set forth in this manual.
To ensure the furnace is on a level foundation and above any possible dampness, a cement pad is recommended.
It is important that the top be level. Install as close to the chimney as possible so that a minimum of pipes and
elbows may be used.
If unit is installed in an enclosed area (furnace room), ventilation must be provided for the burner – minimum of
one square inch for every 1,000 BTU.
1. The NEWMAC COMBINATION FURNACE may be installed with the supply or return air on either side. The
units leave the factory with the return or cold air on the right when viewed looking at the oil burner end. If
it simplifies the duct installation to have the supply air on the opposite side, remove the installed panel and
install it on the other side.
2. After placing the heat exchanger on the proper side of the pad, assemble the blower section to the heat
exchanger section by lining up the already punched holes and metal screwing together.
3.
Install the oil nozzle in the burner firing assembly, and check to make sure adjustments are as shown. Install
the oil burner by mounting it on the burner mounting plate. Check to make sure the oil burner tube is aligned
with the hole in the combustion chamber.
4. Install junction box, fan/limit control, draft fan and thermostat as shown. Note recommended setting.
In order to prevent short cycling, the heat anticipator in the thermostats must be set at 0.4 amps as indicated in
the diagrams below.
NOTE: For constant fan operation, push the MANUAL-AUTO switch on button to MAN position.

Return Air is “otherwise certified” to be installed as per CSA B139
Clearances (Unlined Joist Space may be used for the Return Air as there
is no radiation in the Return Air section)
WARNING: The heat anticipator will BURN OUT IF 25 volts are applied directly to thermostat by shorting out
primary control during testing or incorrect wiring. If this happens the warranty on the thermostat is void.
