NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE
Non-concealed gas connections may be made using the
entry points at either end of the firebox or the one in
the bottom of the firebox . A concealed gas connection
may be made using the knock out hole in the center
back of the firebox . Select the most appropriate entry
point and knock out the rel evant hole in both the firebox
and the outer casing .
No more than 59" of 1/4" diameter pipe must be used
to avoid unnecessary pressure drops .
If a concealed gas con nection is to be made, the supply
pipe should always be sleeved through walls and floors
using the shortest possi ble route .
For concealed supply pipe routing, pipes must (where
possible) be ver tical and providing there is sufficient
wall thick ness available, they should be placed in pipe
chases . Horizontal pipe runs should be avoided where
possible . Prior to chasing a solid wall, an inspection
should be made to note the proximity of any cables/
sockets outlets which may already be buried . Pipes
must be secured using suitable clips and protected
against corrosion . Ideally factory finished protected
pipe-work and fittings should be used . Joints should
be kept to a minimum and compression fittings must
not be used . The pipe-work installation must be tested
for soundness before any protection is applied and/or
the pipe-work and fittings are buried .
