Permanent screws that attach valve assembly to wall plate
should
never be loosened or removed.

will void warranty and may create a dangerous
condition.
Locating the gaslamp
always mount gaslamp on an open wall. never mount gaslight in a
boxed-in or recessed area.
Wall Bracket Assembly (Ref. #1) must be mounted so that
Heat Deflector (Ref. #15) is a minimum of four inches from a
combustible surface, and outside of Globe (Ref. #13) is a minimum
of three inches from a combustible surface to either side or in
front. Mounting gaslamps too close to a door may subject delicate
mantles to vibrations and could damage the mantle.
Mounting & Assembly
1. Remove all packaging materials from gaslamp.
2. Locate gaslamp according to minimum clearances described
below:
3. Connect approved copper tubing to gas inlet using proper
fitting. It is easier to connect the tubing before fastening wall
bracket assembly to wall. Valve assembly (Ref. #2) must be
straight on the wall bracket assembly. Orifice (Ref. #4) must
aim into the center of the Bunsen Burner Venturi (BBV) (Ref.
#28) for proper air and gas mixture.
a knockout tab (twist out using pliers) in the valve cover
is provided for connecting the gas line through the
bottom of the valve cover.
4. Fasten wall bracket assembly to wall using four mounting
screws (Ref. #26) supplied.
cautiOn:
to provide adequate air circulation, the mounting bosses
must not be embedded into the wall. do not overtighten
screws.
5. Attach valve cover assembly (Ref. #27) to wall bracket assembly
by engaging slots on the valve cover assembly with wall
bracket assembly tabs.
6. Mount gaslamp by carefully swinging down the valve cover
assembly so that the slots in the bottom of valve cover engage
Lock Screws (Ref. #12).
7. Tighten valve cover lock screws.
8. Loosen globe lock screw (Ref. #14) and remove globe. Be sure
that all packaging material has been removed.
9. Install mantles:
a. Pre-formed mantle: Grasp ceramic ring – do not touch
mantle itself. Hook legs into reverse “L” of the burner
head.
b. Tie-on mantle: Loop the tie-on strings at the opening of
the mantle. Enlarge the opening so that it will fit over the
ceramic burner head and seat in lower groove of burner
head. Do not tie the mantle to the BBV. Distribute mantle
evenly around the burner head. Pull the ends of the string
so that mantle and string are seated securely in the burner
head groove. Knot and clip off excess string.
10. Attach globe by engaging tabs and inserting globe so that
lock screw can be tightened into the neck of the globe. Do not
over-tighten.
