SECTION A:
WOOD OR WOOD/ELECTRIC COMBINATION FURNACES
Take note that this furnace operates like an EPA wood burning stove. This applies to the lighting, the ember bed,
and the minimum combustion air intake which was determined based on the use of good seasoned cordwood.
The Max Caddy furnace was tested and approved according to the CSA B415.1-10 Standard.
To optimize the efficiency of your furnace, here is some advice that you should follow when installing or operating
your Max Caddy.
Respect the local codes (when in doubt, consult your local dealer);
Make sure your furnace is installed according to the instructions on the certification label;
All controls and adjustments must be performed by a qualified technician. The blower speed must conform
to the recommendations of local codes and should respect the static pressure ranges in the warm air
plenum of the furnace.
We recommend that our wood burning hearth products be installed and serviced by professionals who are certified
in the United States by NFI (National Fireplace Institute®) or in Canada by WETT (Wood Energy Technical Training)
or in Quebec by APC (Association des Professionnels du Chauffage).
1. CHIMNEY AND DRAFT
This furnace must be connected to a chimney certified for use with wood burning heating appliances. A 7-inch
chimney and connector are recommended for the Max Caddy if it is used as a wood-oil unit or a wood-oil-electric
unit. If an oil option may be installed in the future, we also recommend a 7-inch chimney. If the furnace is to be
used as a wood only unit, then a 6-inch chimney is recommended.
The unit is not to be connected to a chimney flue serving another appliance.
If the chimney draft exceeds 0.06 IN.W.C., a barometric draft control should be installed on the smoke pipe. Never
install a manual damper.
The barometric control must be adjusted so that the maximum draft measured at the furnace outlet does not exceed
-0.06 IN.W.C. Please note that a draft exceeding 0.06 IN.W.C. will reduce the efficiency and could produce an
uncontrollable fire. On the other hand, the minimum draft required is 0.04 IN.W.C. in the evacuation pipe on
the wood side, no matter what type of furnace (WOOD, WOOD / ELECTRIC OR WOOD / OIL).
The adjustment should in no case be modified to increase combustion.
