BGD278 Series BASOTROL®

CE Approved Gas Valve

Installation

IMPORTANT: These instructions are intended as a

guide for qualified personnel installing or servicing

BASO Gas Products. Carefully follow all instructions

in this bulletin and all instructions on the appliance.

Limit repairs, adjustments, and servicing to the

operations listed in this bulletin or on the appliance.

WARNING: Risk of Fire or Explosion.

The system must meet all applicable local, national,

and regional regulations. Improper installation may

cause gas leaks, explosions, property damage, and

injuries.

WARNING: Risk of Fire or Explosion.

To prevent leakage of upstream gas, shut off the gas

supply at the main manual shutoff valve before

installing or servicing the BGD278 valve. 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.

Mounting

CAUTION: Risk of Equipment Damage. To

prevent damage to the valve when mounting to

pipework, do not use a wrench on any surface other

than the casting flats provided at the inlet and outlet

ends of the valve body.

To install the BGD278 valve:

1. Ensure that the specified maximum ambient

(surface) temperature is not exceeded (see the

Technical Data section).

2. Ensure that the power supply voltage is compatible

with the required control valve voltage.

3. When installing the valve on the manifold, ensure

that the gas flows through the valve body in the

direction indicated by 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.

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

5. Mount the valve to the pipework. The BGD278

valve may be mounted on a horizontal manifold

with the solenoid coils pointed up (vertical) or in any

position not exceeding 90° from the vertical. The

valve also may be mounted on a vertical manifold

in any position around its axis (see Figure 1). Do

not install the solenoid coil upside

down. Install

vertically wherever possible.

90° Maximum

from Vertical

90° Maximum

from Vertical

Limited Horizontal and Vertical

Vertical mounting may

be 360º around its axis

with the gas flow either

up or down, but always in

the direction of the arrow.

6. 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. 11. Check for leakage at the bleed hole. Paint the bleed hole with a rich soap and water solution (or use acceptable gas leak detection equipment).

Disconnect the power supply before making electrical connections to avoid electrical shock or equipment damage. Ensure that the operating voltage is identical to the information on the product identification label. The BGD278 valve is supplied with 3-tab or 2-tab electrical connections. The solenoid coil has male tabs, and electrical connections should be made using 1/4 in. (6.35 x 0.
