Testing, Commissioning & Use - Nu-Flame Vitesse H.E. Use, Installation & Servicing Instructions

18. - TESTING, COMMISSIONING & USE
! IMPORTANT NOTE !
18.1 - LIGHTING THE FIRE
a. Reference to Section 2 in the Users Instructions 'Lighting & Controlling the Fire' will show how to light and operate the fire.
b. Check that the supply pressure to the fire is at the pressures rquired, 20mbar (Natural Gas G20) or 37mbar (Propane G31) when
set at high.
! IMPORTANT NOTE !
18.2 - TESTING FOR SPILLAGE
a. A restrictor is supplied with the fire for flues that have an effective height greater than 3 meters. The restrictor must not be
fitted to Pre-cast Flue applications. The restrictor is fitted into the duct above the glass panel with the 2 # No6 x 10mm
pointed self tapping screws provided, see below.
b. Once the fire is operational the installer must check for spillage. Carry out the lighting procedure and turn the fire to high. Allow to
warm up for 5 minutes and then using a smoke match, joss stick or similar, place it centrally in the duct above the glass panel as
shown above. The majority of the smoke must be drawn into the duct. Some small whiffs of smoke may be expelled and this is
quite normal. Be careful not to introduce too much smoke (i.e. by using a pellet). A smoke match tube can be used to make
holding of the match easier. See following diagram.
c. Repeat the test with doors and windows to the premises/room both open and closed, and with any extractor fans in the same
room or adjacent rooms running at high. The fire should continue to clear its combustion products. Also operate any other flued
appliance in the same or neighbouring rooms and ensure they continue to function satisfactorily as multiple flues can work
against one another.
d. If spillage is detected during this procedure, remove the restrictor if fitted and repeat the tests.
e. If spillage is detected and no restrictor is fitted, let the fire operate for a further 10 minutes and re-check.
f. If the fire continues to spill, it could indicate a faulty flue or lack of ventilation. If the problem cannot be rectified immediately,
disconnect the fire, affix a label and advise the customer not to use it until the problem has been resolved.
g. It is an offence to use or allow the use of a dangerous appliance.
18.3 - FITTING THE PIPEWORK COVER PLATE (MANUALLY CONTROLLED FIRES ONLY)
For manually controlled fires a black cover plate is supplied to cover some of the pipework and associated fittings under the burner
tray. This is freestanding and is supplied for cosmetic purposes only. The controls can be operated with the cover in place. Please
refer to the photographs in section 2.1
During its first period of use any protective coatings and oils will burn out of the fire and it is wise
to ventilate the room for the first hour; also advise the customer that this may persist for the first
few days until the fire is fully burnt-in.
Ensure that the pressure test point used is sealed and gas tight.
