Jetmaster Mark 4 Gas Log

Jetmaster gas logs are fuel effect appliances intended for

recommended that the Jetmaster gas log be placed in a
properly installed Jetmaster Convector firebox in order
to ensure an adequate draught and greater efficiency.
The Jetmaster open fire is an approved open fire to
burn wood. The following size fireboxes are available
for the Type 1 Burner to be inserted into.The firebox
can be installed into an existing fireplace subject to the
chimney being the appropriate size and in sound
condition. The firebox can also be installed from new
with a gather and a flue.

Commissioning Procedure
Installed correctly the burner should not emit any
fumes into the room. The following procedure should
be undertaken to test that the unit is operating
correctly.
1. After unit has been operating for a short period a
smoke match, smoke tube, carbon dioxide analyser or
similar should be directed at the top opening of the
unit.
2. This procedure should be undertaken with the
following conditions in the room:
• Open or closed windows
• Operation of extraction/exhaust fans, range
hoods etc
• Operation of other gas appliances
• Operation of optional appliance fan at any speed.
3. Should any spillage be detected the cause must be
rectified before allowing commissioning of unit.
