HeatPack Furnace Installation and Operation Manual

WARNING

ACORDING TO THE NATIONAL BUILDING CODE, THE BTU/H PROVIDED BY AN

OUTLET ON THE PLENUM MUST NOT EXCEED 10,250 BTU/H (3KW) AND THE

HOT AIR TEMPERATURE AT THE OUTLET OF A SECONDARY DUCT SHOULD

NOT EXCEED 158 °F (70 °C).

7.3.2 Static pressure calibration

Once your hot air distribution system is installed, make sure to measure the static pressure

in the plenum. Adjust the opening at the end of each of distribution duct with a shutter (not

included) until you get a static pressure 0.2" W.C. (50 Pa) at the plenum.

7.4 Air return system and filter

The installation of an optional air return duct connected to the blower housing will improve

the air circulation throughout the house (see Appendix 3: Optional Air return adapter

(AC01392).

The use of the air filter option is also recommended. The filter option will significantly

reduce dust circulation within the hot air duct and will prevent obstruction of the blower and

the ducts. (see Appendix 2: Optional air filters (AC01390, AC01391))

Take note that the static pressure calibration should be re-done after installing

filters.

8 Combustion air

WARNING

 SUFFICIENT COMBUSTION AIR MUST BE AVAILABLE AT ALL TIMES; LACK

OF COMBUSTION AIR CONSTITUTES A DANGER.

 A CARBON MONOXIDE (CO) DETECTOR/ALARM IS REQUIRED IN THE ROOM

IN WHICH THE FURNACE IS INSTALLED.

A fresh air supply may be necessary to prevent solid fuel units from rejecting products of

combustion into the house.

Additional combustion air can be provided following the following methods, provided that

they satisfy chapter 4 of the CSA B365 standard for Canada:

Direct combustion air supply:

The HeatPack is not certified to be connected directly to a new combustion air supply.

Indirect combustion air supply:

o New combustion air can be brought into a pipe located within approximately 12" (305

mm) of the unit. If the pipe is too close to the furnace, it may interfere with its

operation;

o The recommended diameter of the outside air intake pipe is 4" (102 mm);
