ü
The best location for your fireplace is determined by considering the location of windows, doors, and
the traffic flow in the room where the fireplace is located, allowing space in front of the unit for the
hearth extension and the mantel, and taking into consideration the location of the hot air ducts, outside
air kit (if so equipped), and chimney. If possible, you should choose a location where the chimney will
pass through the house envelope (interior walls).
ü
Usually no additional floor support is needed for the fireplace. The adequacy of the floor can be
checked by first estimating the weight of the fireplace system. Weights are given in the appendix.
Next, measure the area occupied by the system. This will normally be 42” X 23” (1067 X 584 mm) for
the fireplace. Note the floor construction as to the sizes and type of flooring and joists, and then
consult your local building code to determine if additional support is needed. It is your responsibility to
determine the weight load for additional facing materials such as brick or rock.
ü
The
MAGNUM ZC
can be installed above the floor level on a base, (see Hearth Extension
Requirements) provided that there is a minimum of 7’ (2135 mm) measured from floor to the ceiling.
This allows adequate room for venting and ductwork.
ü
If you are installing the fireplace on an exterior wall, the wall must be insulated the same as the other
walls in the home. If this is not done there will be excessive cold air transfer into the home.
OUTSIDE AIR REQUIREMENTS
During operation, the fireplace requires air for combustion and will draw air out of the house. It may
starve other fuel burning appliances such as gas or oil furnaces. As well, exhaust fans and fan driven
appliances may compete for air, causing a negative pressure in the house and resulting in smoke entering
the home from the appliance. This situation is aggravated in modern airtight houses. To overcome this
potential problem, you must install an Outside Air Kit with the
MAGNUM ZC
. The kit is mandatory in
most areas. Check with your local building authority for requirements in your area.
The outside air kit
must be installed according to the following guidelines:
ü
The maximum length of duct is 25’ (6.1 m). Duct length should be kept to a minimum. If duct length is over 10’
increase the size to 6”. Do not have over 3 elbows.
ü
The air intake vent must not be installed more than 7’ (2135 mm) above the base of the appliance.
ü
The fresh air must come from outside the house. It must not draw air from the attic or basement.
ü
Locate the outside vent where it will be well away from automobile exhaust fumes, gas meters, or other vents.
ü
The air intake vent should be installed where it is not likely to be blocked by snow or exposed to extreme wind.
ü
The duct and vent may be installed above or below floor level.
ü
Use only factory approved MAGNUM ZC components.
ü
Cannot terminate in an attic or crawl space.
Secure all connections with screws to prevent them from coming apart and leaking cold air. All piping should be insulated.
