This replace is a vented product. This replace
will not produce any gas leakage into your home
if properly installed. This replace must be
properly installed by a qualied service person.
If this unit is not properly installed by a qualied
service person, gas leakage can occur.
CarbonMonoxidePoisoning: Early signs of
carbon monoxide poisoning resemble the u,

piping system during any pressure testing of
that system at test pressures in excess of 1/2
psig (3.5 kPa).
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve during any pressure
testing of the gas supply piping system at
test pressures equal to or less than 1/2 psig
(3.5 kPa).
For the purpose of input adjustment two

SELECTING LOCATION
To determine the safest and most efcient
location for your appliance, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances (see clearance information on
page 10).
2. Consider a location where heat output
would not be affected by drafts, air con-
ditioning ducts, windows or doors.
3. A location that avoids the cutting of joists
or roof rafters will make installation easier.
Figure 1 shows a plan view of a few com-
mon locations.
Flush installations are recommended where
living space is limited or at a premium and
since the space required to enclose the ap-
pliance would be located beyond an outside
wall, this would also reduce the cutting of
joists, roof rafters and such. Check local
codes for any restrictions.
Projected installations can extend any
distance into the room. A projection may
be ideal for a new addition on an existing,
nished wall.
Corner installations make use of space
that may not normally be used and provides
a wider and more efcient range for radiant
heat transference.
Internalwallinstallations provide a discreet
option for room separation and can also be
ideal as an addition to an existing wall.
