3.3.2. Outdoor installation with chimney
Further considerations regarding outdoor installations:
1., The appliances must not be installed in the reach of
inflammable or explosive gases.
2., They must not be located in air streams containing any
of the gases of the following chemicals: Freon, calcium-
chloride,
potassium-chloride, carbon-tetra-chloride,
chlorine, halogens refrigerants, per chlorine-ethylene,
trichlorine-ethylene,
hydrochloric-acid, ethylene-
dichloride, and photo chemicals. Such air is not harmful
for humans but the chemicals in it react with the gas
flame creating corrosive materials, which shorten the
lifetime of any gas appliance.
3., They must be saved from mechanical injury or other
damages due to illegal entering. (Low brick wall, safety
post, fence, etc.)
4., They must be located so that they could not cause any
damage to the environment in case the pressure relief
valve opens.
5., Employ a proper gutter-overhang to avoid that the
roof water could flow on the appliance! If you want to
raise a roof over the appliance for any reason (falling ice,
etc.) it must have at least three sides open and the lower
edge of the roof must be at least 1 m higher to the top of
the outdoor vent kit.
6., Appliances installed outdoors must be mounted on a
level, structurally sound surface that is not combustible
and at least 100 mm higher to its environment to prevent
that precipitation could gather under the appliance. It is
not reasonable or advised that the base would reach over
the ground-space of the appliance. In case the base would

reach over, care must be taken that it cants toward the
sides to divert rainwater from the appliance. The use of
frost-proof concrete is recommended or a structural steel
construction is advised when the weight matters.
7., Outdoor running pipes are advised to be heat insulated
and their length to be minimized. (Heat insulating the pipes
alone is not enough protection against freezing.)
8., The rest of the heat engineering equipment is advised
to be installed inside the building except some proper IP
protected pumps, flow switches, level switches,
thermostats, sensors for stage controllers, air purging
valves, etc.
