BLUE FLAME PROPANE/LP GAS HEATER

Figure 14 - Gas Connection
* A CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Purchase the optional CSA/AGA design-certified
equipment shutoff valve from your dealer. See Accessories, page 17.
INSTALLATION
Continued
CONNECTING TO GAS
SUPPLY
The installer must supply an external regu-
lator. The external regulator will reduce
incoming gas pressure. You must reduce
incoming gas pressure to between 11 and 14
inches of water. If you do not reduce incom-
ing gas pressure, heater regulator damage
could occur. Install the external regulator
with the vent pointing down as shown in
Figure 13. Pointing the vent down protects
it from freezing rain or sleet.
WARNING: A qualified service
person must connect heater to gas
supply. Follow all local codes.
CAUTION: Never connect heater
directly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
Typical Inlet Pipe Diameters
VP2000BTD 3/8" or greater
VP2800BTD 1/2" or greater
Installation must include equipment shutoff
valve, union, and plugged 1/8" NPT tap.
Locate NPT tap within reach for test gauge
hook up. NPT tap must be upstream from
heater (see Figure 14).
IMPORTANT:
Install an equipment shutoff
valve in an accessible location. The equip-
ment shutoff valve is for turning on or
shutting off the gas to the appliance.
CAUTION: Use only new,
black iron or steel pipe. Inter-
nally-tinned copper tubing may
be used in certain areas. Check
your local codes. Use pipe of large
enough diameter to allow proper
gas volume to heater. If pipe is
too small, undue loss of pres-
sure will occur.
Install sediment trap in supply line as shown
in Figure 14. Locate sediment trap where it
is within reach for cleaning. Locate sedi-
ment trap where trapped matter is not likely
to freeze. A sediment trap traps moisture
and contaminants. This keeps them from
going into heater controls. If sediment trap
is not installed or is installed wrong, heater
may not run properly.
IMPORTANT:
Hold the pressure regulator
with wrench when connecting it to gas pip-
ing and/or fittings.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.

Apply pipe joint sealant lightly to male
threads. This will prevent excess sealant
from going into pipe. Excess sealant in pipe
could result in clogged heater valves.
WARNING: This appliance re-
quires a 3/8" NPT (National Pipe
Thread) inlet connection to the
pressure regulator.
