Gas Line Installation; Remote Switch Installation - Vermont Castings DBT33 Installation Instructions & Homeowner's Manual

AS INE
When purging the gas lines, the front glass must
be removed.
The gas pipeline can be brought in through the rear of the
replace as well as the bottom. Knockouts are provided on the
bottom behind the valve to allow for the gas pipe installation
and testing of any gas connection. It is most convenient to
bring the gas line in from the rear right side of the valve as
this allows fan installation or removal without disconnecting
the gas line.
The gas line connection can be made with properly tinned
3/8" copper tubing, 3/8" rigid pipe or an approved ex con-
nector. Since some municipalities have some additional local
codes it is always best to consult your local authority and the
CAN/CGA-B149 (.1 or .2) installation codes.
For U.S.A. Installations consult the current National Fuel Gas
Code, ANSI Z223.1
Always check for gas leaks with a mild soap and
water solution. Do not use an open ame for
leak testing.
The gas control is equipped with a captured screw type pres-
sure test point, therefore it is not necessary to provide a 1/8"
test point up stream of the control.
When using copper or ex connectors use only approved t-
tings. Always provide a union when using black iron pipe
so that the gas line can be easily disconnected for burner or
fan servicing. See the gas specication for pressure details
and ratings.
The replace valve must not be subjected to any test pressures
exceeding 1/2 p.s.i.. Isolate or disconnect this and any other
gas appliance control from the gas line when pressure testing.

Installation
1. Thread the wiring through the holes on the end panels of
the appliance. Take care not to cut the wire or insulation
on metal edges. Route the wire to a conveniently located
receptacle box.
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
3. Connect the other ends of the wire to the gas control valve
as shown in Fig. 6.
Alternative Switch Location
The remote switch can be installed on the front/side of the
access door. Simply mount the switch to the bracket provided
and screw the bracket to either side of the frame, lining up the
screws with the pre-punched holes, Fig. 7.
Do not wire the remote ON/OFF wall switch for
the gas replace to the 120 volt power supply.
