CONVERSION KITS

In the event your Hestan appliance needs to be converted

from NG to LP, or vice-versa, you will need to contact

Hestan Customer Service to arrange a service call. This

conversion should only be performed by a qualified

technician.

HIGH ALTITUDE KITS

If you live in a high altitude area, 2,000 ft. [610 m] or more

above sea level, your appliance may require different orifices

for proper combustion and performance. You will need to

contact Hestan Customer Service to arrange a service call.

High Altitude kits must be installed by a qualified technician.

Please have your model and serial number information ready

when you call.

GAS CONNECTION - NATURAL GAS (NG)

To ensure proper heating performance of this appliance,

verify that the gas line supply pressure is adequate. The

appliance is supplied with a gas pressure regulator already

installed. This regulator is set for a supply (inlet) pressure of

7-14 inch WC [1.74-3.48 kPa] to maintain 5 inch WC [1.24

kPa] nominal outlet (manifold) pressure. Ensure that the

service pipe supplying the appliance is fitted with a shut-off

valve conveniently positioned and easily accessible as an

emergency gas shut-off.

GAS CONNECTION - LIQUID PROPANE (LP)

If you purchased an LP version of your appliance, it will be supplied with a gas pressure regulator

already installed. This regulator is set to maintain 10 inch WC [2.49 kPa] nominal outlet (manifold)

pressure. Ensure that the service pipe supplying the appliance is fitted with a shut-off valve

conveniently positioned and easily accessible as an emergency gas shut-off.

When connecting to LP gas, verify the tank is equipped with its own high pressure regulator. The

pressure of the gas supplied to the appliance must be 11-14 inch WC [2.74-3.48 kPa].

LEAK TESTING

GENERAL

Although all gas connections on your Hestan appliance are leak tested at the factory prior to

shipment, a complete gas tightness check must be performed at the installation site due to possible

movement in shipment, or excessive pressure unknowingly being applied to parts of the unit.

Immediately check if the smell of gas is detected. Leak testing of the appliance shall be conducted

according to these instructions:

BEFORE TESTING

DO NOT SMOKE WHILE LEAK TESTING.

• Never leak test with an open flame.

• Make a soap solution of one part liquid detergent and one part water for leak testing purposes.

• Apply the solution to the gas fittings and flex hose by using a spray bottle or a brush.

TO TEST

• Make sure all control knobs are in the “OFF” position.

• Apply the soap solution to all fittings and flex hose.

• Turn the gas supply on.
