General Information
Your MagicPak All-In-One™ HVAC system HWC8/HWC9
unit is unique in that it is entirely self-contained in one
compact cabinet. It uses outside air for gas combustion
and the products of combustion are exhausted by a power
vent directly to the outside through the upper left corner
of the exterior grille. If your unit is located at ground level
or so the exterior is on a balcony, you will able to observe
the ue products discharge area. On cold mornings during
the heating cycle you may notice a vapor emitting from the
discharge area. This is normal.
Depending on your local or state building codes, you will
have a power disconnect either adjacent to your unit or
located at your main electrical panel. Overcurrent protection
will be provided at this point. Have your builder, dealer or
maintenance personnel show you how to turn the power on
and o for your MagicPak unit.
A eld-supplied gas cock (external manual shut o valve)
is located in the gas line entering the top of your unit. For
unit operation, the handle of the valve must be manually
turned so it is in a parallel position to the gas line. This is
the “OPEN” position.
Your unit is equipped with an energy saving, automatic,
intermittent ignition system. The burners are automatically
ignited at the beginning of each heating cycle and shut o
when each cycle is completed. Your unit does not have a
pilot requiring manual lighting.
For your safety - Read before operating
If you do not follow these instructions exactly, a re
or explosion may result, causing property damage,
personal injury or loss of life.
Should overheating occur or the gas supply fail to shut
o, turn o the manual gas valve to the appliance before
shutting o the electrical supply.
Before operating, smell around the appliance area for
gas. Be sure to smell next to the oor because some gas
is heavier than air and will settle to the lowest point. Refer
to “What to do if you smell gas” on page 1 if the odor of
gas is present.
The unit area must be kept clean and free of combustible
materials, gasoline and other ammable vapors and
liquids.
