Always try to get the stove as low as possible in the boat, this will allow
installation of maximum length flue pipe.
Always have two double walled, above deck extensions, short for cruising and
long (28inch minimum) for mooring. Insulated extensions are a thing of the
future but it is possible to fill the space using a vermiculite and cement mix
sealed off with flexible fire putty.
Fit a rotary swinging cowl to each extension or make one interchangeable.
Clean or have the chimney cleaned regularly. (Frequency depends upon type of
fuel and length of time used).
Loss of chimney vacuum can also be caused by-:
Faulty Stove seals.
Door seals, Glass seals, Pot to closure plate seal, damaged door glass.
Bad deck flange fitting.

If the plumbing circuit is not of a suitable design, it will not be possible to carry
out the commissioning procedure as the burner may well shut down due to
overheating of the boiler.
Always check that water is flowing freely through the boiler.
If the oil valve safety stat shuts the burner down, check the temperature of
the boiler outlet flow pipe.

1. Generally this is caused by the action of the safety stat, which shuts off the
flow of oil to the appliance from the oil control valve.
This will be observed via a tripped off oil valve.
