INSTALLATION

GAS PIPE PRESSURE

TESTING

The appliance must be isolated from the gas

supply piping system by closing its individual

manual shut-off valve during any pressure

testing of the gas supply piping system at test

pressures equal to or less than 3.45 kPa.

Disconnect piping from valve at pressures over

3.45 kPa.

The manifold pressure is controlled by a regu-

lator built into the gas control, and should be

checked at the pressure test point.

Note: To properly check gas pressure,

both inlet and manifold pressures

should be checked using the valve

pressure ports on the valve.

1) Make sure the valve is in the "OFF" position.

2) Loosen the "IN" and/or "OUT" pressure

tap(s), turning counterclockwise with a

1/8" wide flat screwdriver.

3) Attach manometer to "IN" and/or "OUT"

pressure tap(s) using a 5/16" ID hose.

4) Light the pilot and turn the valve to "ON"

position.

5) The pressure check should be carried out

with the unit burning and the setting should

be within the limits specified on the safety

label.

6) When finished reading manometer, turn off

the gas valve, disconnect the hose and

tighten the screw (clockwise) with a 1/8"

flat screwdriver. Note: Screw should be

snug, but do not over tighten.

leak testing.

GAS LINE

INSTALLATION

The gas line can be brought through either the

right, the left side or the bottom of the appliance.

The gas valve is situated on the bottom of the

unit.

The gas line connection may be made of rigid

pipe, copper pipe or an approved flex connec-

tor. (If you are using rigid pipe, ensure that the

valve can be removed for servicing.) Since

some municipalities have additional local codes

it is always best to consult with your local

authorities and AS5601-2004 (Australian

Installation Code) NZS 5261(New Zealand

Installation Standard).

When using copper or flex connectors use

only approved fittings. Always provide a union

so that gas lines can be easily disconnected for

servicing. Flare nuts for copper lines and flex

connectors are usually considered to meet this

requirement.

Periodically check the pilot flames. Cor-

rect flame pattern has three strong blue

flames: 1 flowing around the thermopile,

1 around the thermocouple and 1 flowing

across the burner (it does not have to be

touching the burner).

Note: If you have an incorrect flame pat-

tern, contact your Regency dealer

for further instructions.

Incorrect flame pattern will have small,

probably yellow flames, not coming into

proper contact with the rear burner or

thermopile or thermocouple.
