PART 2 - SECTION I - INSTALLATION INSTRUCTIONS

Raypak recommends a minimum length of

vertical flue of three (3) metres to ensure

correct draft.

OUTDOOR INSTALLATIONS.

An outdoor heater must not be installed inside

any roofed structure or under eaves, roof

overhangs, or pool decks. It should also be at

least 1500 mm, in any direction from any

window or fresh air opening.

When installing the heater on a raised base,

please make sure that the base material is

solid and filled in. E.G. If steel mesh decking is

used, a suitable plate material must be used to

fill in the perforations. This is very important, as

any excessive drafts must not be able to enter

the unit from directly underneath.

HIGH WIND CONDITIONS

On rare occasions or in areas where high

winds frequently occur, it may be necessary to

locate the heater a minimum of one (1) metre

from high vertical walls, or install a wind break

so that the heater is not in direct wind current.

Models 538 to 1852, where the installation

may cause "Down draft", Raypak can supply a

Wind Deflection Plate (at extra cost), to

eliminate constant ignition failures or flame

disturbance, the need for which would be

determined by an approved Raypak Service

Person or Agent.

In areas of "constant extreme winds" or where

a Wind Deflection Plate is not appropriate, it

may be necessary to replace the "standard"

low profile outdoor hood with a HIGH WIND TOP

which would be at extra cost.

The HIGH WIND TOP serves the same function

as the low profile outdoor hood and should be

installed in accordance with the same

clearance requirements.

GAS SUPPLY

The gas supply pipe must be sized to give

sufficient pressure for the correct operation

of the heater. The gas line must be fitted

with an isolation valve. Consult AG 601 for

further details.

Caution: The gas supply must be isolated from

the heater during pressure testing of the gas

fitting line.

Dissipate test pressure before reconnecting to

the heater.

Failure to follow this procedure may result

in damage to the gas valve. (Over

pressured valves and equipment are not

covered by our warranty.)

The heater and it's gas connection must be

thoroughly leak tested before placing in

operation. Use soapy water and a manometer

for leak test.

DO NOT USE NAKED FLAME.

WATER CONNECTIONS AND

SYSTEM PIPING

The heater must be installed to the appropriate

and/or local codes. For typical piping systems

and heater applications it is essential that

Raypak be consulted, Raypak heaters do have

some special requirements and if you are not

familiar with Raypak products we can save you

unnecessary inconvenience!

Water pipe connections to heater are:

538 to 1292 - 50 mm copper slip fit or 2" NPT,

1362 to 1922 - 80mm BSP and

2004 to 4224 - 100 mm BSP.

Do not reduce the pipework size and heater

water connections without allowing for any

friction loss which will occur. Low water flow

will cause damage to the heater and system

components. Please install pipework using

approved fittings and isolating valves that will

allow easy disconnection for any future

maintenance requirements.

Use a minimum of one (1) metre of copper or

stainless steel tube for the final connections to

the heater inlet and outlet.

NEVER CONNECT LOW TEMPERATURE PVC

PRESSURE PIPE DIRECTLY TO THE HEATER.

A non-return valve must be installed on the

inlet side of the heater, after the filter.
