INSTALLATION
Continued
IMPORTANT:
The appliance and its individual
shutoff 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 kPa). The appliance must be isolated
from the gas supply piping system by closing its
individual equipment 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).
CAUTION: Do not kink flex
-
ible gas line.
CAUTION: Compounds used
on threaded joints of gas piping
shall be resistant to the action
of Liquefied Petroleum (LP or
propane), and should be applied
lightly to ensure excess sealant
does not enter the gas line.
1. Install a sediment trap between the incoming
gas line and the gas control valve (see Figure
39). The sediment trap should extend down the
center of the pipe. Refer to your local codes.
2. Prepare incoming gas line and check with
local codes regarding the use of teflon tape.
Complete your gas line installation by con-
necting incoming gas line with flexible gas
line. Secure tightly with a wrench, but
DO
NOT OVERTIGHTEN.

WARNING: All gas piping
and connections must be tested
for leaks after the installation
is completed. After ensuring
that the gas valve is open, ap
-
ply a soap and water solution
to all connections and joints. If
bubbles appear, leaks can be de
-
tected and corrected. Do not use
an open flame for leak testing
and do not operate any appliance
if a leak is detected.
WARNING: Improper installa
-
tion, adjustment, alteration, ser
-
vice, or maintenance can cause
injury or property damage. Refer
to this manual. For assistance or
additional information, consult
a qualified installer, service
agency, or gas supplier.
GAS SUPPLY TESTING
Note:
This section is intended as a guide for
qualified service technicians installing gas to the
appliance.
CAUTION: Do not connect
appliance before pressure test
-
ing gas piping. Damage to the
gas valve may result and an un
-
safe condition may be caused.
The millivolt system with a manual HI/LO ap-
plies only to the DVF36TCR, DVF36TCRP,
DVF36TCL and DVF36TCLP models. The gas
control valve is accessible from the lower control
compartment. Two pressure taps are provided on
the gas control valve for a pressure gauge connec-
tion (see Figure 40, page 23).
The electronic system applies to the DVF36T-
CRE, DVF36TCRPE, DVF36TCLE and DVF36T-
CLPE models (see Figure 41, page 23).
