Connect Gas Supply; Test For Gas Soundness; Install Fuel Effect; Replace Glass Door - Valor 474 Valentia Installation And Owner's Manual

NOTE: The flue and air ducts do not need cutting unless the short flue assembly is
being fitted. In this case measure the wall thickness. Then subtract this length from
203mm to give the length 'B' shown in Fig. 4B. Cut this length from the plain ends of
both the inner flue and the inner air ducts.
(c) Adjust the flue length: First measure the wall thickness and add 140mm to give the
overall length of flue 'A'. Fit the terminal assembly to the ducts already fitted to the
heater. The top of the assembly is marked 'TOP'. Set the overall length of the flue to
the dimension 'A' (Fig. 4A). Drill 2.7mm diameter for the fixing screws but do not fit
them yet. Remove the flue terminal.
(d) Slide the sealing rope gasket and the sealing plate over the air duct as shown in
Fig. 4C. Refit the terminal and secure it with the screws provided. Seal the joints
using the self-adhesive tape provided.
(e) Remove the tape from the foam sealing strip on the terminal. Do not remove the
tape before the fire is ready to be installed as the foam strip commences to expand
once the tape is removed. The rate of expansion however, is low and there will be
adequate time to install the heater, after which the foam strip will continue to expand
and fill the gap between the flue and the wall. If for any reason the sealing strip has
already expanded before the heater is installed, it can simply be compressed by hand
until it is flush with the surface of the flue.
(f) Insert the two top wall fixing screws, leaving the plain shank projecting to allow the
keyhole top fixing holes to go over them. Offer the fire with the flue through the wall
and hook the keyholes over the screws. Insert the lower wall fixing screws and secure
all four screws.
(g) If a terminal guard is required (optional extra) fit it with the kit supplied ensuring
that it is concentric with the terminal.
7.3 Connect to Gas Supply (Using rigid or semi rigid tubing incorporating a service
cock)
With the outer case removed, the gas inlet pipe is located at the right hand side of the
fire. Connect the fire to the gas supply via the union elbow provided. This union elbow
should be fitted to the end of the supply pipe and then held in position onto the flare
whilst this is engaged. Tighten the flare nut with a spanner. The union elbow has Rp¼
(¼ in B.S.P. internal) thread for supply pipe.
7.4 Test for Gas Soundness (Refer to BS 6891 : 1988)
The gas installation, including the meter, should be inspected and tested for
soundness and purged.
7.5

Install Fuel Effect

Remove the coal effect from its pack. The coal effect is a one piece assembly and
has a 'tunnel' cut out at one end. Fit the coal effect so that this tunnel is over the pilot
burner on the right side of the firebox. The coal effect should come to rest on the full
length inner front support and also on the two rear coal supports.
7.6

Replace Glass Door

Refit the glass door ensuring all studs protrude through the door evenly. Replace the
wingnuts and tighten evenly.
