Technical information

Fixed ventilation should be provided to avoid draughts as far as possible

without impairing the free area of ventilation, even in adverse weather conditions.

All permanent openings for ventilation should be designed to prevent the entry

of vermin. Where screens are provided, they should not have apertures of less

than 6 mm. or greater than 9 mm. in any direction, and they should be accessible

for cleaning. Fine mesh screens should be avoided as they are liable to become

blocked with dust.

The location of vents and the method of cleaning them should be stated in the

Owners Handbook (Caravans and Boats).

As a guide, the minimum effective free area of vents is stated below in connection

with this water heater. Additional appliances burning gas in the same area would

require additional air requirements.

1. If a D61B, D61E or G11E is installed in an enclosed space in a Caravan

Holiday Home the required ventilation is that as specified in BS 5482 part 2,

ie 10 cm

per kilowatt input rating divided between high and low. So the high

and low vents should be 55,5 cm

for D61B, D61E and 114 cm

for G11E.

2. Where a D61B or D61E is installed in an open bottomed cupboard in a

Caravan Holiday Home, i.e. in a kitchen, the ventilation requirements is as

stated in BS 5482 part 2. (EN 721).

A.2.2.B PUTTING AN APPLIANCE INTO SERVICE

Checks:

Check that the main water and gas supplies meet the specifications given on

the appliance’s technical specification plate. Take special care to ensure that the

water and gas pressures are correct. Also make sure that the bottle regulator is

large enough to allow sufficient gas to be supplied to the appliance, bearing in

mind the gas consumption of other appliances on the same meter.

• FIXING THE APPLIANCE

To do this you only need to remove the cover. Proceed as follows:

• Remove the control knobs.

• Remove the screw securing the front of the cover, hidden by the temperature

selector control button.

• Remove the screw (2) which secures the cover to the base, at the bottom.

• Remove the cover from the lugs which secures it to the top of the base.

Having selected a location for the water heater in accordance with the

requirements set out in this Manual, the water heater should be fixed to the wall

using the mounting holes on either side of the base plate.

• PUTTING THE APPLIANCE INTO SERVICE

• Before connecting up the appliance, it is necessary to purge the water and gas

pipe work thoroughly, in order to remove filings and other waste material.
