
In Cana
da, this furnace must be installed according to CSA standard B365 “Installation Code for Solid-Fuel Burning Appliance
and Equipment.“

For connection to an oil furnace refer to, CSA Standard B139 “Installation Code for Oil Burning Equipment” for Canadian
requirements.

In the United States, this furnace must be installed according to NFPA 211, Standard for Chimneys, Fireplaces, Vents, and
Solid Fuel-
Burning Appliances“ and NFPA 90B, “Standard for the Installation of Warm Air Heating and Air-Conditioning
Syst
ems.”

For connection to an oil furnace refer to, NFPA31 “Standard for the Installation of Oil Burning Equipment” for US requirements.

This furnace is designed to burn wood only unless equipped with a Newmac Pellet burner.

DANGER: RISK OF FIRE OR EXPLOSION, FOR SAFE OPERATION:

Load fuel carefully or damage may result

Do not load solid fuel higher than the firebox liner

Do not use chemical or fluid fire starters

On combination units: Do not attempt to light a fire when there is oil vapour present

Minimum flue draft -
.03” W.C.

Maximum flue draft -
.05” W.C.

Do not burn garbage, manufactured fire logs, gasoline, naphtha or crankcase oil or other inappropriate materials

Keep the furnace door tightly closed except for refueling and cleaning

Maintain all door seals in good condition

To maintain furnace efficiency and prevent soot fires, clean the heat exchanger, flue pipes and chimney at the end of each
heating season to minimize corrosion during summer months and as frequently as required during the heating season to
prevent soot accumulation. The furnace, flue and chimney must be in good condition. These instructions also apply to a draft
inducer if used. Turn off power to the furnace when cleaning the furnace and flue.

Do not store fuel or combustible material within the furnace clearances.

Do not use salt wood (Driftwood gathered from the seashore).
WARNING: TO PREVENT DAMAGE AND RISK OF FIRE

Do not set the flue draft above -
.05” W.C. as the fire could burn out of control.

If equipped, do not open the furnace door slide plate damper during normal operation.

Furnaces require a minimum of 2” of sand or wood ash in bottom of firebox.
CAUTION: HOT SURFACES

Keep children away

Do not touch during operation
SPECIAL PROCEDURES:
POWER FAILURE
1. Turn off power supply to furnace; remove the access door and air filters for better air circulation. If the furnace
is in an enclosed area (furnace room) open the door to the room. Turn power switch back on after filters are
reinstalled
2. If equipped, to control the fire, open the slide damper in the furnace door or the lower primary air control. THE
SLIDE DAMPER IN THE FURNACE DOOR SHOULD BE CLOSED FOR NORMAL OPERATION. THE
LOWER PRIMARY AIR CONTROL SHOULD BE OPEN FOR NORMAL OPERATION.
3. Do not load the firebox higher than half way up the firebrick or cast liner as overheating may result
SOOT FIRE
Close all sources of air that can reach the fire through the furnace and draft regulator. Insure the draft fan above the
fire door is turned off. Do not attempt to take the flue pipes down until the fire has been completely extinguished.
RUNAWAY FIRE
This can be caused by too high a flue draft or excessive fueling.
1. Close all sources of air to the furnace. Insure draft fan is turned off.
2. Set the barometric draft regulator wide open to reduce draft. The excessive heat caused by a runaway fire
may damage the furnace safety controls. Their operation should be checked before the furnace is returned to
service.
After a soot or runaway fire inspect chimney connection and chimney.
