1.1 GAS APPLIANCES

In the interests of your safety and that of others it

is a requirement that all gas appliances are in-

stalled and correctly maintained by a competent

person and in accordance with the latest regula-

tions.

1.2 ELECTRICAL SUPPLY

Please ensure that this appliance has been prop-

erly connected to the electrical supply by means

of a double pole isolator or un-switched socket,

and that the correct size of fuse (3 amp) has been

fitted.

Warning: This appliance must be earthed!

1.3 GUARANTEE REGISTRATION CARD

Please take the time to fill out your guarantee

registration card. The completed warranty card

should be posted within 30 days of installation.

1.4 HOW DOES IT WORK?

Your Rain/Rain bi boiler is a central heating boiler,

which supplies heated water to your radiators and

hot water cylinder.

It is controlled by the time clock or programmer

and any thermostats that your installer may have

fitted.

The Rain/Rain bi lights electronically and does

not have a pilot light.

In the unlikely event of a fault developing with your

boiler, the supply of gas to the burner will be

terminated automatically.

GETTING STARTED

2.1 BEFORE SWITCHING ON

Before switching the appliance on please familiar-

ise yourself with:

●how to isolate the appliance from the gas,

water, and electricity supplies

●how to check and top-up - if necessary - the

system water pressure

●the time clock or programmer

●any external thermostats and their functions

●the appliance controls.

2.2 APPLIANCE CONTROLS (see fig. 1)

The appliance has a mode switch, variable ther-

mostat, system pressure gauge. The mode switch

has three positions:

●Reset

●Off

●On

The variable thermostat allows you to set the

temperature of the water to your radiators and hot

water cylinder (not the hot water to your taps!)

between 40ºC (min) and 80ºC (max).

The pressure gauge shows the current pressure

of the system, the gauge should be set between

1 and 1.5 BAR. When the appliance is operating

the gauge may rise or fall slightly, this is quite

normal. The minimum permissible level for the

safe and efficient operation of the appliance is 0.5

bar. Should the pressure fall below 0.5 bar, the

boiler shuts off automatically.

Depending on the type of controls specified by

your installer an external time clock or program-

mer may have been fitted, please refer to the

instructions supplied with such.

2.3 LIGHTING THE BOILER

Ensure the gas and electrical supply to the boiler

are turned on.

Turn the mode switch to the ‘on’ position. Refer to

the particular instructions for the type of program-

mer or time clock fitted and ensure there is a

demand for heating and/or hot water. If there is a

room thermostat and/or hot water cylinder ther-

mostat you should ensure these are also calling

for heat.

When there is a demand for heating and/or hot

water via the above controls the boiler will go

through an ignition sequence, whereby the burner

will light.

If the appliance fails to ignite during the ignition

sequence, allow a period of two minutes before

re-setting.

To adjust the output temperature of the appliance

turn the thermostat knob clockwise to increase or

anti-clockwise to decrease.

When the appliance reaches the set temperature,

the burner will go off for minimum period of ap-

proximately 3 minutes.

When the programmer/time clock or external ther-

mostats heating request has been satisfied, the

appliance will switch off automatically.

HOW TO...

3.1 HOW TO TOP-UP THE SYSTEM PRESSURE

(fig. 2)

The system pressure must be checked periodi-

cally to ensure the correct operation of the boiler.

The needle on the gauge should be reading

between 1 and 1.5 bar when the boiler is in an off

position and has cooled to room temperature. If

the pressure requires ‘topping-up’ use the follow-

ing instructions as a guide.

●Locate the filling valve connections (external to

the boiler).

●Attach the filling loop to both connections.

●Open the filling valve slowly until you hear water

entering the system.

●Close the filling valve when the pressure gauge

(on the boiler) reads between 1 and 1.5 BAR.

●Remove the filling loop from the connections.

3.2 HOW TO RESET THE APPLIANCE

When the reset light is illuminated the appliance

will require to be reset manually. Using the mode

switch, turn it two clicks to the left (reset position)

then turn it back to the ‘on’ position.

Allow a period of two minutes to elapse before

turning the mode switch to the reset position.

IMPORTANT

If the appliance requires to be reset frequently, it

may be indicative of a fault, please contact your

installer or Vokera Customer Services for further

advice.

3.3 HOW TO SHUT DOWN THE SYSTEM FOR

SHORT PERIODS

The system and boiler can be shut down for short

periods by simply turning the programmer or time

clock to the off position (see pages 6-10 or the

instructions supplied). It is also advisable to turn

off the main water supply to the house.

3.4 HOW TO SHUT DOWN THE SYSTEM FOR

LONG PERIODS

If the house is to be left unoccupied for any length

of time – especially during the winter – the system

should be thoroughly drained of all water. The

gas, water and electricity supply to the house

should also be turned off. For more detailed

advice contact your installer.

3.5 HOW TO CARE FOR THE APPLIANCE

To clean the outer casing use only a clean

damp cloth. Do not use any scourers or abra-

sive cleaners.
