|CARE & USE/INSTALLATION
The heater is factory set to use either propane (LP) or
natural gas (NAT). This heater is dedicated to one of these
two gas types and it is not easily field convertible. It is
critical that the gas you use matches that which the heater
was set up for. You can verify that by checking the rating
plate.
The Rating plate lists model/serial numbers and gas type.
The rating plate is located in the following places:
• Attached to the top of the heater housing
• Inside the valve compartment, behind the access cover
Ensure that the gas supplied meets with the minimum
pressure requirements. Do not operate the heater on any
gas other than that for which the heater has been set.

Water Column Requirements
It is important that the inlet gas piping system be size
properly for the gas appliance that it serves. Please use the
above chart for verification of the Gas Inlet Pressure
required for this product.
NATURAL AND LP GAS
All gas connections must be made by a qualified
technician, specifically trained in the installation
of this type of gas appliance. Some states or
provinces require this trained personnel be licensed.
Installations must be performed in accordance with
local codes, or in the absence of local codes, the
regulations governed by that state or provincince.
To ensure satisfactory performance, the gas suppply
line must be sized to accommodate the total BTU
requirements of all the gas-fired equipment that will be
connected to that line.
Additionally, each ‘T’ or elbow that is added to the line
can also reduce pressure. This drop in pressure can affect
overall heater performance.
• Calculate the total BTU output of all equipment and refer
to “Gas Supply Line Runs” for allowable run distances for
¾ inch pipe. Failure to meet these minimum requirements
may reduce performance of the heater and any other
appliances running on that supply line.
• Always keep supply line runs as short as possible.
• A minimum pipe size of ½” is required for inlet
piping. The supplied exit coupling of this heater is
½”NPT (female). A ½” lever-handled, manual gas
shut-off valve should be installed within 6 feet of the
appliance to allow emergency gas shut-off and provide
isolation for servicing.
• A gas shut-off valve must be installed in an easily
accessible location by a qualified plumber.
• Keep threading compound off of the first two pipe
threads to avoid having any small pieces of compound
break loose and clog a burner valve or orifice.
• All gas pipe connections to the heater must be sealed
with gas pipe compound or Teflon sealing tape. Prior
to use, the gas supply line should be checked for leaks
by applying a mild solution of soap and water. Never
use an open flame to check for leaks. See section titled
‘Checking for Gas Leaks’ on page 17.

IMPORTANT NOTE: There is a pressure tap built into the
valve system used on the Lynx Eave Mount Patio Heater.
To access this tap, remove the 2 screws which hold the
louvered plate on the END CAP of the heater. Remove this
plate and look for the 2 smaller, slotted, brass screws. The
uppermost screw is the OUTLET pressure (as seen when the
heater is pointed downward). The lower screw is the INLET
pressure. To access either inlet for taking measurements,
turn the screw until it becomes loose. It will not fall out, as,
it is captivated in the valve. Be sure to re-tighten screw after
pressure measurements have been taken (see pg 29).
