CAUTION: Do not connect
appliance before pressure test
-
ing gas piping. Damage to gas
valve may result and an un
safe
condition may be caused.
The appliance and it’s individual shutoff valve
must be disconnected from gas supply 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
pressure taps (for IN and OUT pressures)
are provided on the gas control valve for test
gauge connections to the appliance.
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,
finished wall.
Corner installations
make use of space
that may not normally be used and provides
a wider and more efficient 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.
seleCtING loCatIoN
To determine the safest and most efficient
location for your appliance, you must take into
consideration the following guidelines:
1. The location must allow for proper clear-
ances (see
Clearances
, page 7).
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.
