H15 Series BASO® 100% Shutoff,

Automatic Pilot Valve

Application

The H15 Series pilot valves provide safe lighting and

complete shutoff of pilot and main burner gas on a

variety of domestic and commercial gas burning

equipment. Applications include room heaters, wall

heaters, unit heaters, central heating equipment, crop

dryers, dish washing machines, industrial ovens, and

degreasing equipment.

Installation

IMPORTANT: Only qualified personnel should

install or service BASO Gas Products products.

These instructions are a guide for such personnel.

Carefully follow all instructions in this document and

all instructions for the appliance.

IMPORTANT: Make all gas installations in

accordance with applicable local, national, and

regional regulations.

CAUTION: Risk of Electrical Shock.

Disconnect power supply before making electrical

connections to avoid electrical shock

Note: In applications that do not require electrical

power, disregard the above caution.

WARNING: Risk of Explosion or Fire.

Shut off the gas supply at the main manual shutoff

valve before installing or servicing the H15. Failure

to shut off the gas supply can result in the release of

gas during installation or servicing, which can lead to

an explosion or fire, and may result in severe

personal injury or death.

IMPORTANT: Verify that the valve is installed

only in applications where the specified maximum

ambient (surface) temperature and maximum

operating pressures do not exceed the limits in the

Technical Specifications section.

To install the H15 valve:

1. Shut off power to the appliance (if applicable).

2. Shut off the gas at the main manual shutoff valve.

3. Ensure that the main gas flow through the gas

valve body must be in the direction indicated by

either “IN” and “OUT” or the arrow on the valve

body. If the valve is installed with the gas flow in

the opposite direction of the arrow, leakage can

occur.

IMPORTANT: Do not use a wrench on any

surface other than the casting flats provided at the

inlet and outlet ends of the valve body. The H15 may

be damaged in the mounting process if a wrench is

used on any other surface. Using a wrench

incorrectly may void the warranty.

4. Mount the valve to the pipework. The H15 valve

may be mounted in any convenient position. Use

an approved pipe joint sealing compound on the

male threads before assembly. Remove excess

compound after mounting the valve to the

pipework. Threads of the pipe and nipples must

be smooth and free of tears and burrs. Steam

clean all piping to remove foreign substances

such as cutting oil or thread chips. A sediment

trap should also be installed in accordance with

the National Fuel Gas Code (ANSI Z223.1). (See

Figure 1 and Figure 2.)

5. Attach the thermocouple securely to the pilot

burner, and screw the terminal end to the BASO®

power unit terminal on the valve. Make sure this

connection is clean. Tighten the thermocouple

lead nut finger tight, plus a maximum of 1/8 turn.

Do not overtighten.

6. Pilot gas connections. a. Internal Pilot Gas Valve Models receive pilot gas internally from the valve body. Note: Pilot gas flow comes out of either gas valve top housing ports. On internal pilot gas valve models, plumb the pilot burner fitting to either of the pilot gas ports on the valve. Plug the unused pilot gas port on the gas valve. See Figure 1 and Figure 2. b. ! WARNING: Risk of Explosion or Fire. Verify that there are no gas leaks by testing with appropriate equipment.
