Step 1. LOCATE VENT OPENING
(Requires 3-1/2" diameter wall opening).
a) Select area on wall where heater will be installed. Using
template (packed with heater) mark shaded area where
hole can be cut and to locate the wall brackets. (See
Figure 4).
b) Locate studs on each side of this area.
c) Mark location for 3-1/2" diameter hole between studs.
Hole should be offset to miss studs. (See Figure 4).
d) Check outside wall at this location for proper clearances

Drip Leg
Install a drip leg in gas supply line immediately upstream from
the gas connection to heater (see local codes), and provide
a 1/8" N.P.T. plugged tapping, accessible for test gauge
connection and an individual manual shut off valve accessible
within room where heater is installed. (See Figure 5). The heater
and its individual shut off valve 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 Pa). The
heater must be isolated from the gas supply piping system by
closing its individual manual shut off valve during any pressure
testing of the gas supply piping system at test pressures equal
to or less than 1/2 psig (3.5 Pa). Test all connections for leaks
using a soapy solution. NEVER USE AN OPEN FLAME TO
TEST FOR LEAKS.
