Building and Installation Work
All building and gas installation should be carried out by a qualified and
competent person, and must adhere to national and local legislations and
regulations.
Before Starting
READ PAGE 4 FIRST
Building work should only commence after a thorough survey of the intended
location of the impending installation has been completed and it has been
established that the unit can be installed and operated without risk to the
owner or tenants of the property or their neighbours.
Where existing chimney systems are to be used in conjunction with the FIRE
RIVER, they should have been swept and undergone thorough examination to
ensure that they are in a sound and safe condition, as well as providing an
adequate draw when the gas fire unit is in operation.
A simple smoke test will reveal whether or not the chimney is working
correctly.
Check gas pipe work to ensure the correct flow rate for the appliance.
This fire is approved for use with a Class 1 or 175mm Flue System with either
2 metres for Natural Gas or 3 meters for LPG minimum length. If a flue system
in excess of the specified length is used this may cause a very strong draw to
occur which will result in the flame being effected. It is normal for the flame to
be angled towards the back of the enclosure.
Burner ventilation can be provided by a slot behind the optional fascia trim. If
this is not fitted additional ventilation will need to be planned. See Page 14
Once installed all additional gas inlet holes in the enclosure [not the front vent]
must be sealed with metal tape to avoid flame reversal which will damage the
remote.
The enclosure and flue must be sealed inline with building regulations.
Failure to ensure the correct flue and burner ventilation requirements are met
as outlined in this manual will result in damage to the fire which is not covered
by the warranty.
It is important that the gas supply is disconnected before any old
existing surround and hearth is removed.
