CAST IRON STOVE AND BURNER SYSTEM
105501
CDVBN(A) AND CDVBP(A)
Figure 39 - Gas Connection
* The A.G.A. design-certified manual shutoff valve may be supplied with the appliance or
you can purchase it from your dealer.
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 1/2"
diameter or greater to allow
proper gas volume to burner sys-
tem. If pipe is too small, undue
loss of pressure will occur.
Installation must include a manual 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
burner system (see Figure 39).
IMPORTANT:
Install main gas valve
(manual shutoff valve) in an accessible lo-
cation. The main gas valve is for turning on
or shutting off the gas to the appliance.
Check your building codes for any special
requirements for locating manual shutoff
valve to stoves.
For propane/LP connections only, the in-
staller must supply an external regulator.
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 incoming gas
pressure, burner system regulator damage
could occur. Install external regulator with
the vent pointing down as shown in Figure
38. Pointing the vent down protects it from
freezing rain or sleet.

Installation Items Needed
Before installing stove and burner system,
make sure you have the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• manual shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con-
nector (if allowed by local codes) (not
provided)
* An A.G.A. design-certified manual shutoff
valve with 1/8" NPT tap is an acceptable
alternative to test gauge connection. Pur-
chase the A.G.A. design-certified manual
shutoff valve from your dealer.
WARNING: A qualified ser-
vice person must connect burner
system to gas supply. Follow all
local codes.
CAUTION: For propane/LP
units, never connect burner sys-
tem directly to the propane/LP
supply. This burner system re-
quires an external regulator (not
supplied). Install the external
regulator between the burner sys-
tem and propane/LP supply.
CAUTION: Use pipe joint seal-
ant that is resistant to liquid pe-
troleum (LP) gas.

We recommend that you install sediment
trap/drip leg in supply line as shown in
Figure 39. Locate sediment trap/drip leg
where it is within reach for cleaning. Install
in piping system between fuel supply and
burner system. Locate sediment trap/drip
leg where trapped matter is not likely to
freeze. A sediment trap traps moisture and
contaminants. This keeps them from going
into burner system gas controls. If sediment
trap/drip leg is not installed or is installed
wrong, burner system may not run properly.

CHECK GAS TYPE
Use proper gas type for the burner system
you are installing. If you have conflicting
gas types, do not install burner system. See
dealer where you purchased the stove and
burner system for proper burner system
according to your gas type.
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 burner system valves.
