Newmac CL 170C - Notice; Special Procedures - Power Failure

15
IMPORTANT
• This furnace must be installed according to CSA Standard B139 “Installation Code for Oil Burning Equipment”.
Furnace must be installed as per Newmac clearances. Venting must be installed according to CSA Standard
B365 “Installation Code for Solid Fuel Burning Appliances and Equipment”.
• The solid fuel side of this furnace is designed to burn wood only, unless equipped with grates thus allowing
the burning of coal. Burn anthracite coal only.
• Proper ue draft must be maintained to allow combustion gases to ow freely out the chimney.
• ONLY chimney approved for wood burning may be used, ie. ULC S629-650 C, UL 103 or masonry chimney is
acceptable.
FOR SAFE OPERATION
• Load fuel carefully or damage may result.
• Do not load solid fuel higher than the re box liner.
• Do not use chemical or uid re starters.
• Do not attempt to light a re when there is oil vapour present.
• Minimum ue draft - - .03” W.C.
• Maximum ue draft - - .05”W.C.
• Do not burn garbage, manufactured re logs, gasoline, naptha or crankcase oil.
• Keep the furnace doors tightly closed except for refueling and cleaning.
• Maintain all door seals in good condition.
• To maintain furnace efciency and prevent soot res, clean the heat exchanger, ue pipes, and chimney
at the end of each heating season and as frequently as required during the heating season to prevent
soot accumulation. The furnace and ue must be in good condition. Turn off power to the furnace when
cleaning the furnace and ue.
• Do not store fuel or combustible material within the furnace clearances.
• Do not use salt wood (driftwood gathered from the seashore).
TO PREVENT DAMAGE
• Do not set the ue draft above -- .05” W.C. as the re could burn out of control.
• Do not open the furnace door slide plate damper during normal operation.
• Furnaces with grates must have ashes removed daily.
• Furnaces without grates require a minimum of 2” of sand or ash in the bottom of the re box.
SPECIAL PROCEDURES - POWER FAILURE
1. Remove the blower access door and air lters for better air circulation. If the furnace is in an enclosed area
(furnace room) open the door to the room.
2. To control the re open the slide plate damper in the furnace door. THIS DAMPER SHOULD BE CLOSED FOR
NORMAL OPERATION.
3. Do not load the re box higher than half way up the re box liner.
SOOT FIRE
Close all sources of air that can reach the re through the furnace and draft regulator. Ensure the draft fan
above the re door is turned off. Do not attempt to take the ue pipes down until the re has been completely
extinguished.
RUNAWAY FIRE
This can be caused by too high a ue draft or excessive fueling.
1. Close all sources of air to the furnace. Ensure draft fan is turned off.
2. Set the barometric draft regulator wide open to reduce draft. The excessive heat caused by a runaway re
may damage the furnace safety controls. Their operation should be checked before the furnace is returned
to service. After a soot or runaway re inspect chimney connection and chimney.
CONVERSION OF CL115/170 C & G TO 5 TONS A/C
• 3/4” HP Motor Recommended.
• 7” X 3/4” Blower Pulley Recommended (Standard is 8”).
• 41” Blower Belt required for 7” pulley.
• See A/C wiring diagram with Honeywell 8405A Relay (or equivalent).
• Install a By-Pass damper or blast as per sketch “Typical A/C Coil Installation”.
