3.7 Gas Connection
3.7.1 Gas Piping Guidelines
Follow all local codes and/or the most recent edition
of the National Fuel Gas Code (ANSI Z223.1/NFPA
54) in the USA or the Natural Gas and Propane
Installation Code in Canada (CAN/CSA B149.1).
3.7.2 Gas Supply Lines Pressures
Note warning applies to this entire section.
Δ The minimum and maximum inlet gas pressures
for Natural Gas - Min. 3.5”WC – Max. 10.00”WC.
Δ The minimum and maximum inlet gas pressures
for Liquid Propane Gas Min. 8.00”WC – Max.
13.00”WC.
Δ Gas pressures over and above the specied
range will result in adverse performance and
dangerous operating conditions; any damage
resulting from extreme gas supply pressures will
not be covered by the limited warranty.
Δ Until pressure testing of the main gas supply
line is completed, ensure the gas line to
the Glow T180 tankless water heater is
disconnected to avoid any damage to the water
heater.
Δ The appliance and its individual shut off valve
must be disconnected from the gas supply
piping system during any pressure testing of that
system at test pressures in excess of 0.5 psi (3.5
kPa).
Δ The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply system at test
pressures equal to or less than 0.5 psi (3.5 kPa).
Δ The gas appliance and it’s gas connections must
be leak tested before placing the appliance in
operation. Leaks can be found by using a gas
leak detection device or by applying soapy water
to all gas ttings. Should bubbles occur, tighten
those connections and re-test.
Δ Always purge the gas line for any debris before
connecting to the water heater gas inlet.
Δ Never use an open ame to test for gas leaks as
property damage, personal injury or death could
result.
Δ The maximum inlet gas pressure must not
exceed the valve specied by the manufacturer
and the minimum valve listed for the purposes of
input adjustment.
Δ The connection to the gas supply must be
carried out by professionally qualied personnel
in accordance with the relevant standards.
Δ Check the internal and external seals of the gas
supply system.
Δ A gas shut-off valve must be installed upstream
of the appliance.
Δ Before starting up the water heater, make sure
that the type of gas corresponds to that for which
the appliance has been set-up.
Δ The gas supply pressure must be between the
values reported on the rating plate.
Δ If the power supply wire is damaged in any
way, switch off the appliance and have the wire
replaced by a qualied electrician.
When using an electrical appliance:
Δ Do not touch the appliance with damp or wet
parts of the body or when barefoot.
Δ Do not pull on the electric wires.
Δ Do not allow the appliance to be used by
children or anyone unfamiliar with it’s operation.
