Theappliance and it’sindividual shutoffvalve
must be disconnected from the 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.

locationforyour appliance, you musttakeinto
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. Alocation that avoids the cutting of joists
orroofrafters will make installationeasier.
Figure 1 shows a plan view of a few com-
mon locations.
Flush installations arerecommendedwhere
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.

PENETRATING ROOF
To maintain a 1" clearance to pipe on a roof
with a pitch, a rectangular opening must
be cut.
1. Determine center point where pipe will
penetrate roof.
2. Determine center point of roof. Pitch is
the distance the roof drops over a given
span,usually 12".A6/12 pitch means that
the roof drops 6" for each 12" measure
horizontally down from roof rafters.
3. Use roof opening chart (Figure 16) to
determine correct opening length and
