TO TURN OFF

THE HEATER

1. Turn the heater ON/OFF power

isolation switch to the "OFF" position.

EMERGENCY SHUT-DOWN

1. Turn "OFF" the power supply to the heater

2. Turn "OFF" the gas isolation valve fitted

close to the heater or the main gas supply.

AFTER START-UP WARNING

Should overheating occur or the gas supply fail

to shut off, turn off the gas isolation valve

located adjacent to the heater turn off the

power supply switch and call for assistance.

VISUAL INSPECTION FOR DANGER!

Keep the heater area free from chemicals,

combustibles and flammable materials.

Do not obstruct the flow of ventilation air into

the plant room.

Regularly clean the heater cabinet air louvres of

any dust, lint and debris.

Failure to follow these safety precautions can

cause fire, explosion, or asphyxiation.

With the heater turned on and heating, remove

the door (if fitted) and make a visual check of

the burners. The flame should be blue with a

well-defined pattern.

A yellow or floating flame indicates restricted air

openings, incorrect orifice size or possible

excessive draft. Continual yellow flames indicate

some restriction of the combustion air openings.

A bright orange, luminous flame is not normal and

can cause sooting under prolonged operation.

Observe for any indication of soot. The

presence of soot accumulation would indicate

an abnormal operating condition.

Should any abnormalities occur, turn the

heater off and contact your installer or

service organisation.

WARNING: Operation of the heater when faulty

will result in rapid and severe damage to the

heater, which is not covered by our warranty.

SERVICE ASSISTANCE

Service must only be undertaken by properly

authorised personnel.

It is a requirement of all Raypak and all gas

authorities that the heater be serviced at least

once per year, where it is used in a specific

application, e.g. heating, it would be practical

to perform the service at the commencement

of the heating season, or at any time there may

be an indication of a problem.

This service should include the cleaning of the

gas burners, inspection of waterways, and

checking of all controls for correct operation.

It is important and very often will save time if

you state the model number, serial number and

type of gas used. This information will be found

on the heater data plate.

Your local Raypak distributor will arrange for

your service or recommend a qualified

service organisation or visit:
