The boiler is suitable for use with natural gas and propane*. For other
types of natural gas, consult our Technical department. All gas
appliances must, by law, be installed by competent persons. Failure to
install appliances correctly could lead to prosecution.
It is in your own interest and that of safety to ensure that the law is
complied with.
The gas connection is at the top of the boiler. We recommend
installing a gas filter in the gas supply pipe to avoid pollution of the
gas multiblock. The gas filter's resistance must not be so high that the
minimum inlet gas pressure can no longer be achieved.
Gas installation instructions
1. A main gas shutoff valve should be connected to the boiler within
accessible area and within hand reach.
2. A sediment trap must be installed upstream of the main gas
shutoff valve.
3. The boiler gas train (valve) does not require venting or bleeding, a
VPS can be used in jurisdiction where required.
The boiler and the individual shutoff valve must be leak tested
according to local and national gas installation codes B149 & ANSI
Z223.1. If the leak pressure testing exceeds 1/2 psi (35 mbar) the
boiler and the individual gas shutoff valve shall be isolated and
disconnect during this test.
* OEM gas conversion kit required (optional).
The boiler has been factory set and tested to natural gas (G20) -
with an inlet pressure of 7 inches w.c.(17 mbar).
Higher gas supply pressure(s) require a separate service regulator.
Natural gas supply inlet pressure range 3.5 - 14 inches w.c. (< 0.5
psi) [8.7 - 35 mbar) is required.
For propane (LPG), an inlet pressure of 8 - 13 inches w.c. (< 0.5
psi) [20 - 32 mbar) is required.
