Location - COZY 90N30A Instrucciones De Instalación Y Funcionamiento

FIG. 1
Choose a central
location such as a
hallway but where
occupant traffic is
minimal & where
there is at least 18
inches of room from
two adjoining sides of
the grill to the nearest
wall so that occupants
may pass without
stepping on the grill.
See Figure 1.
Give consideration to available air for combustion, location in relation to chinmey or vent system, thermostat location, clearance
under floor, clearance to combustibles, and heat circulation. Any open foundation is unacceptable as wind can cause pilot outage and
reduced efficiency. Keep furniture, drapes, doors, and other combustible materials at least 12 inches from the edge of the grill. Never
locate the floor furnace closer than 8 inches to a wall and never in a corner. See Figure 2.

Adequate air for combustion and venting must be provided. Any reduction in the necessary amount of fresh air can result in
an oxygen starved flame that emits Carbon Monoxide (C.O.) an odorless, colorless gas that can cause serious injury or death.
A ventilated crawl space will usually provide enough fresh air. However, you must
check to see that there is 1 square inch of free area of ventilation opening for each
1,000 BTU's input of your floor furnace.
To compensate for the loss of square inches of ventilation due to the use of
louvers, grills, or screens add approximately 50% to the square inches calculated.
Screen all openings with mesh not less than 1/4 inch to prevent animals or insects
from entering the crawl space.
All type "B" vents shall ext end in a generally vertical direction with offsets not
exceeding 45 degrees, except that a vent system having not more than one 60
degree offset may be allowed.
Any angle greater than 45 degrees from the vertical is considered horizontal. The
total horizontal run of a vent plus the horizontal vent connector shall be not greater
than 75 percent of the vertical height of the vent.
Any offsets used should be as far above the drafthood as possible to allow a
venting action to begin before any restriction is encountered.

Two adjoining sides of the floor furnace must have a minimum
clearance of 18". See Figure 1.
After selecting a location in the home, go beneath the floor
and check the position of the floor furnace in relation to joists,
supporting columns, electric wires, water pipes and walls. There
must be a minimum of 6 inches clearance between the top of
the draft hood and floor joists. There must also be at least 6
inches clearance between the bottom of the floor furnace and
the ground. See Figure 3.
In order to find the location beneath the floor it may be necessary
to drill a 1/16 inch hole through the floor approximately in the
center of the selected floor furnace location to use as a reference
point when measuring under the floor.
Example 1:
Example 2:
If another gas burning appliance, such as a water heater, is
installed within the same crawl space or basement: Add the
B.T.U.'s of the other appliance to those of the floor furnace
before calculating the total ventilation needed.
