Floor Mounting Away From Wall; Connecting To Gas Supply - Mr. Heater MHVFRD10NG Operating Instructions And Owner's Manual

4. If installing bottom mounting screw into hollow
or solid wall, install wall anchors. Follow steps 1
through 4 under Attaching to Wall using Anchor.
If installing bottom mounting screw into wall stud,
drill holes at marked locations using 9/64" drill bit.
5. Re-place heater onto mounting bracket.
6. Place spacers between bottom mounting holes
and wall anchor or drilled hole.
7. Hold spacer in place with one hand. With the
other hand, insert mounting screw through
bottom mounting hole and spacer. Place tip of
screw in opening of wall anchor or drilled hole.
8. Tighten both screws until heater is firmly secured
to wall. Do not over tighten.
Note: Do not re-place front panel at this time.
Replace front panel after making gas connections and
checking for leaks.

FLOOR MOUNTING AWAY FROM WALL:

Installing Support Feet (See figure 11.)
1. Lay heater onto table on its back with bottom
edge overhanging table edge.
2. Securely attach feet to bottom of heater using 2 –
self-tapping screws each.
Figure 11
Note: Feet should have long end going out the front of
heater, and the edge coinciding with side of heater. If
feet overhang side of the heater, switch leg location.
3. Place heater on non-combustible surface (see
Locating Heater, page 6) before proceeding
with gas connection. If this will be a permanent
location, heater may be locked into position using
anchoring holes in mounting feet.
Note: Use of floor mounting feet will require you to
use a 3/8 NPT street elbow to make gas connection.
Unvented Natural Gas Fired Room Heater

CONNECTING TO GAS SUPPLY

WARNING: A qualified service person must connect
heater to gas supply. Follow all local codes.
WARNING: This appliance requires a 3/8" NPT
(National Pipe Thread) inlet connection to the pressure
regulator. Use of floor mounting feet will require
you to use a 3/8 NPT street elbow to make gas
connection.
CAUTION: Never connect heater to private (non-
utility) gas well. This gas is commonly known as well-
head gas.
IMPORTANT: Check your gas line pressure before
connecting heater to gas line. Gas line pressure must
be no greater than 14 inches of water. If gas line
pressure is higher, heater regulator damage could
occur.
CAUTION: Use only new black iron or steel pipe.
Internally-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 pressure will occur.
Installation must include an equipment shutoff valve, union
and plugged 1/8" NPT tap. Locate NPT tap within reach of
test gauge hookup. NPT tap must be upstream from heater
(see figure 12).
*A CSA/AGA certified equipment shutoff valve with
1/8" NPT tap is an acceptable alternative to test gauge
connection. Purchase the CSA/AGA certified equipment
shutoff valve from your dealer.
IMPORTANT: Install an equipment shutoff valve in an
accessible location. The equipment shutoff valve is for
turning on or shutting off the gas to the appliance.
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 fuel train.
CAUTION: Use pipe joint sealant that is resistant to
natural gas.
Install sediment trap in supply line as shown in figure 12.
Locate sediment trap where it is within reach for cleaning.
A sediment trap traps moisture and contaminants. This
keeps them from going into heater. If sediment trap is
not installed or is installed improperly, heater may not run
correctly.
IMPORTANT: Hold pressure regulator with wrench when
connecting it to gas piping and/or fittings.
