INSTALLATION AND OPERATING INSTRUCTIONS DR AFT FOR OEM USE ONLY

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 Teon
®
/ 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 Teon
®
/ 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 Teon
®
/ 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.
The control valve must be in the closed position when the
gas supply line is tested for leakage up to 150 mbar (15 kPa;
2 PSI). Above 150 mbar (15 kPa; 2 PSI) the control valve must
be isolated from the gas supply.
PERFORM PRESSURE TEST
1. Check carefully for gas leaks immediately after the valve has
been installed and the gas turned on. Do this before attempt-
ing to operate the appliance or other gas burning device.
2. Using a clean brush, apply an approved leak test solution to
the tubing and pipe connections. Bubbles indicate a leak.
3. If no leakage is detected, light the main burner.
4. With the main burner in operation, apply an approved leak test
solution to all tubing and pipe connections (including adapters)
and the valve inlet and outlet. Bubbles indicate a leak.
5. If a leak is detected, tighten pipe connections (including adapt-
ers) according to “Gas Connections” (see page 5).

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.

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.
