GAS CONNECTIONS
Fire or Explosion Hazard. Can cause property damage,
severe injury, or death. Do NOT bend tubing at gas valve
connection point after compression tting has been tightened.
This can result in a gas leak at the connection.
Use new, properly reamed pipe free from metal or material chips.
When tubing is used, assure that ends are square, deburred and
clean. All tubing bends must be smooth and free of distortion.
When threads are tightened, the valve must be held at the desig-
nated clamping points (see gure 9, page 5).
Do not overtighten connections. Overtightening can damage
the control body resulting in a leak or a control malfunction.
(see MAXIMUM ALLOWED TORQUE, see page 4)
Main Gas (Tubing Connections)
1. Do not use pipe joint compound. Mertik Maxitrol does NOT
recommend the use of Teon
®
/ PTFE tape.
2. Slip nut and ferrule over tubing.
3. Slide nut and ferrule into place, and insert tubing into inlet / out-
let connection until it bottoms. Turn nger tight.
4. Use a wrench to tighten nut about 1 turn beyond nger tight.
Main Gas (Pipe Connections)
1. Mertik Maxitrol does NOT recommend the use of Teon
®
/ PTFE
tape.
2. Pipe to be inserted into the valve must be the proper thread
length and to gauge. Thread that is cut too long can cause
distortion or malfunction if inserted too deeply. Thread cut too
short can cause thread stripping if over-torqued.
3. Apply a moderate amount of approved pipe sealant to the pipe
only, leaving the two end threads bare.
4. Connect pipe to valve inlet and outlet.
Pilot Gas (Tubing Connections)
1. Do not use pipe joint compound. Mertik Maxitrol does NOT
recommend the use of Teon
®
/ PTFE tape.
2. Slip tting over tubing.
3. Insert pilot tubing into pilot outlet until it bottoms. Turn tting
nger tight.
4. Turn with a wrench until you shear off the ferrule. Turn an ad-
ditional ¾ turn to make a gas tight seal.
5. Connect other end of tubing to pilot burner.
1. Turn off gas supply at the appliance service valve before
starting installation, and perform a Gas Leak Test after the
installation is complete.
2. Install the sediment trap or lter (where required) in the gas
supply line to prevent contamination of the gas valve (see
gure 8, page 5).
3. Use only your hand to push in or turn the gas control knobs.
Never use tools. If a knob will not push in or turn by hand,
do not try to repair it. Call a qualied service technician.
Force or attempted repair will void warranty and can result
in a re or explosion.

MOUNTING POSITION
In upright position, gas control knobs are on top of the valve. Valve
may be mounted 0° to 90° any direction (including vertical) from
the upright position. Valve must NOT be mounted upside down.
LOCATION
Locate the combination gas valve where it is not exposed to
steam cleaning, high humidity, dripping water, corrosive chemi-
cals, dust or grease accumulation, or excessive heat.
To assure proper operation, follow these guidelines:
▪ Locate combination gas valve in a well-ventilated area.
▪ Mount combination gas valve high enough to avoid exposure to
ooding or splashing water.
▪ Make sure the ambient temperature does not exceed the ambi-
ent temperature ratings for each component.
GV60 standard version is suitable for indoor use only.
