GENERAL

The CELT STAR is a gas fired instantaneous water heater. It is designed to deliver hot water through a swivel spout or to a hot water tap at a sink or basin (I F). A remote

model is also available (2 F). A high pressure model is for use directly off the mains, a low pressure model is supplied for use off a tank supply.

The appliance features an atmosphere sensing device which will turn off the gas supply to the pilot and burner, when the oxygen in the atmosphere in the locality of the heater becomes diminished and is unable to support safe combustion. It also protects the user if the heat exchanger fins become blocked.

Also included in the appliance is a scale reducer. Four models are available : Spout model

The water inlet is suitable for connection to a 15 mm copper supply pipe and can be used with either capilla-

ry or compression fittings, The low pressure model can be fed from a tank. The high pressure model must be connected to the mains supply.

The connection to the water section is made as

shown. Use the fibre washer when connecting the copper bend to the water service cock (fig. 3).

1 F model

The distance from the heater to the remote outlet should not exceed 20 feet.

Note : When using the 1 F model it is possible in addition to the spout to supply a remote outlet. A remote outlet bend is supplied and is fitted in place of the blanking disc (fig. 4) however permission from the local Water Authority must be obtained before connecting the HP models of the heater to the main supply.

Ensure that all water connections are fully tightened.

Test pipework for soundness.

4. COMMISSIONING

Open the gas and water service taps (see fig. 6a). Purge the gas and water supplies. Check for gas and water soundness.

Fit the gas and water control knobs and light the pilot by turning 90” anti-clockwise. It way be necessary to wait for the pilot to purge, if so, wait a few moments then turn to the ‘off’ position and repeat.

When the pilot is alight wait 10 seconds then turn the gas control fully anti-clockwise to the main gas position.

Turn on the hot tap, the heater will now light. Check for gas soundness on appliance gas carrying com-

ponents Turn off the gas control knob. Check the burner pressure by removing the screw from

the pressure test point (A) (fig. 5) on the end of the burner manifold. Attach a suitable pressure gauge. Light the appliance and check the pressure. The correct pressure is given in table 1, page 2. If the pressure is not correct, check the pressure at the meter. The gas installation should be examined for any possible blockage if the pressure is not correct. The heat input is pre-set and nonadjustable.

Turn off at the gas control knob, remove pressure gauge, replace the test point screw, relight and check for gas soundness around the screw.

Remove screw on left hand side of combustion chamber to allow the data badge to suspend freely. Replace screw.

4.1 To fit casing

(fig. 6)

a) Remove the control knobs. b) Screw plastic spacer tube onto temperature selector

spindle guide.

c) Hang the side panels from the top deflector plate en-

suring they are engaged in the slots provided (A) (fig.

6).

d) Fasten the rear of each panel to the chassis at the

bottom (B) (fig. 6) using the screws provided and spire clips provided (C).

e) Attach the front panel to the side panels in the same manner.

Replace the gas control knob, and water tap knobs. The temperature selector spindle should be screwed fully clockwise, the knob pushed on with the indicator at the + position.

4.2 Flame failure device

Check the operation of the flame failure device :

By blowing out the pilot The flow of gas to the pilot will cease and the thermoelectric valve should drop out with an audible click, within approx 30 seconds.

With the water running mask the top of the deflector

using a large pan or similar metal plate (fig. 7a). The pi-

lot and main gas should extinguish within 15 seconds.

Fig. 7

4.3 TO check the thermocouple

Check with a BGC multimeter or suitable millivolt meter to determine the thermocouple output under two conditions :

When operating normally - output should be 14 mv or greater.

When the deflector is obscured the thermoelectric valve should close at 5,5 mv.

4.4 Handing over

Hand the Instructions for Use to the consumer and instruct in the correct and safe operation of the heater.

Explain to the user or purchaser that if the appliance is

not used for long periods it is recommended that the ap-

pliance is drained. This is particularly important during the winter months (see servicing instructions for procedure to drain appliance).

Finally, advise the user or purchaser that, for continued

efficient and safe operation of the appliance it is important that adequate servicing is carried out at regular intervals

SERVICING INSTRUCTIONS

6.1 1

Heat input

It is a requirement of the Gas Safety (Installation and Use) Regulations 1984 that the burner pressure and gas rate are checked each time the appliance is serviced, likewise the service engineer should satisfy himself with regard to gas soundness and the adequacy of combustion and ventilation air if this is appropriate.

The heat input is preset and non-adjustable. The heat input and burner pressure should be checked againts Table I.

If the heat input/burner pressure is not correct check the working pressure at the gas meter. The gas installation

should be examined for any possible blockage if the pressures are incorrect.

Routine servicing

For efficient and trouble free operation it is important that the Celt Star receives annual maintenance. This routi-

ne service will normally be confined to : a) Cleaning the burner. b) Cleaning the heat exchanger fins. c) Checking the gas controls. d) Cleaning the pilot tube and sampling tube. e) Cleaning the thermocouple and electrode. f) Greasing the gas valve spindle. g) Checking the heat input.

h) Checking the operation of the atmosphere sensing device. The following schedules are recommended :

a) Before commencing any work turn off : 1) the gas at the service cock,

2) the water at the water service cock by turning clockwise 1/4 turn and check for gas leaks after reassembly.

b) Clean or replace components as necessary. c) Check the function of the appliance and burner pressure after allowing it to warm up throughly. d) Observe the flame picture. Check for flame lift or excessive yellow tips.

6.3 1 Cleaning

a) The burner can be cleaned by inverting and brushing with a soft brush. Inspect injectors, ensure they are

clear.

b) Clean the pilot and sampling tube by blowing through.

c) The heat exchanger flueways can be cleaned by thoroughly brushing the finned surface. After brushing ins-

pect to ensure that the flueways are completely clear.

d) The thermocouple can be wiped with a lint free cloth to remove any deposits. If the thermocouple tip appears

burnt or cracked, exchange to avoid a possible break at a later date.

e) Electrode : examine and clean the tip, if the tip appears damaged replace electrode and lead assembly.

f) Replace all components in reverse order. The gasket between the gas section and the manifold must be cor-

rectly positioned upon reassembly.

6.4

To remove the casing

a) Pull off all the knobs. b) Remove the screws in the base of the front panel and lift off panel. c) Remove the screws at the bottom of the side panels and lift off panels.

Descaling procedure

Periodically it may be necessary to remove scale deposits from the waterways of the appliance to ensure continued and efficient operation. The frequency will depend largely on the hardness of the water.

Use a solution consisting of five parts water to one part hydrochloric acid. The water should preferably be hot,

ADD ACID TO WATER, NOT WATER TO ACID. Advice with regard to descaling is available from Chaffoteaux Ltd (Service Department).
