Gas Conversion Field Assembly Kit

Natural Gas to Liquefied Petroleum (Propane) or
Liquefied Petroleum (Propane) Gas to Natural

Only for use with Slant/Fin boilers equipped with Honeywell VR8200, VR8204, VR8300 and
VR8304 gas valves, either standing (continuous burning) pilots or intermittent ignition
systems.

WARNING

This conversion kit shall be installed by a
qualified service agency in accordance with
the manufacturer’s instructions and all
applicable codes and requirements of the
authority having jurisdiction. If the informa­tion in these instructions is not followed
exactly, a fire, an explosion or production of
carbon monoxide may result causing prop­erty damage, personal injury or loss of life.
The qualified service agency is responsible
for the proper installation of this kit. The
installation is not proper and complete until
the operation of the converted appliance is
checked as specified in the manufacturer’s
instructions supplied with the kit.

WARNING-IMPORTANT

1. This conversion kit is supplied with the
same parts normally provided on
SLANT/FIN factory built boilers which are
Design Certified by CSA International.
However, because we have no way of
applying our own quality control procedures
to field alterations made by others on this
boiler, these alterations are not the respon­sibility of SLANT/FIN. These alterations are
the responsibility of the installer of this con­version kit. The instructions below must be
carefully followed in order to duplicate
factory installation.

WARNING

LIQUEFIED PETROLEUM (L.P.) PROPANE GAS­FIRED BOILER LOCATION

REQUIRES SPECIAL ATTENTION
Liquefied Petroleum (LP) propane gas is heavier
than air. Therefore, propane boilers, piping, valves
must NOT be installed in locations where propane
leaking from defective equipment and piping will
"pool" in a basement or other space below the leak.

A spark or flame from the boiler or other source
may ignite the accumulated propane gas causing
an explosion or fire. Provide a level, solid founda­tion for the boiler. Location should be as near the
chimney as possible so that the flue pipe from boil­er to chimney is short and direct.

THE UNIFORM MECHANICAL CODE may be in
effect in your geographic area.

The following precautions are cited by the 1994
UNIFORM MECHANICAL CODE, section 304.6:

"LPG Appliances. Liquefied petroleum gas­burning appliances shall not be installed in a pit,
basement or similar location where heavier­than-air gas might collect. Appliances so fueled
shall not be installed in an above-grade under­floor space or basement unless such location is
provided with an approved means for removal of

unburned gas."
Consult Chapter 5 of the 1994 UNIFORM
MECHANICAL CODE for design criteria of the
"approved" means for removal of unburned gas.

2. The installation must conform to the require­ments of the authority having jurisdiction or,
in the absence of such requirements, to the
National Fuel Gas Code ANSI Z223. 1-lat­est edition.

The boiler warranty is void unless this field assembly conversion kit has been properly installed,

labels completed and applied to boiler and registration card completed and received

by Slant/Fin within 10 days after kit has been installed in boiler.

BURNER ADJUSTMENT

A. Adjust gas input rate:

1. Consult gas supplier for higher heating value of gas
(Btu/cu.ft.)

2. Set thermostat high enough so that boiler will remain
on while checking rate.

3. Measure manifold pressure at 1/8" tapping. See
label provided with the conversion kit for the correct
manifold pressure for the gas that is being supplied.
NOTE: Gas pressure may be adjusted by turning
pressure regulator screw on combination gas valve
(turn clockwise to increase pressure, counterclock
wise to decrease pressure).
See page 17 for the input rate of your boiler.

a. Input for PROPANE is approximately at rating shown on

rating plate when manifold pressure is 91/2" water
column.

b. Input for NATURAL GAS is approximately at rating

when manifold pressure is 31/2" water column, but
should be checked on the gas meter:

Btuh Input = Btu/cu. ft. x cu. ft. metered

in 3 minutes x 20

Example 1
For 1000 Btu/cu.ft. gas, this becomes:
Btuh Input = cu. ft. metered in 3 minutes

Example 2
For 1050 Btu/cu.ft. gas, this becomes:
Btuh Input = cu. ft. metered in 3 minutes

4. The higher* heating value of gas varies substantially
for different localities. Consult with Slant/Fin’s
Technical Service Dept. for re-orificing procedures
if any of the following apply:
a. Boiler (burner) is overfiring. CAUTION! National

Fuel Gas Code ANSI Z223.1-latest edition does
NOT permit firing at a higher input rate than the
input rate indicated on the boiler rating plate in
order to avoid hazardous conditions such as
explosion or carbon monoxide poisoning.

b. Poor higher* heating value of gas is causing the actual

input to be substantially lower than

:

x 1,000 Btu/cu.ft. x 20

:

x 1050 Btu/cu.ft. x 20

the rating plate

indication.

* “Higher heating” value of gas is commonly known as “heating value”.

model using 1000 Btu/cu.ft. gas is tabulated in the gas rate table.

B. Main Burner

1. Fire the boiler continuously for at least 15 minutes,
to reach burner operating temperature.

2. Observe the flames, all burners. The base of all
flame jets should be blue. The tips should be blue
shading to orange.
NOTE: Dust, disturbed by any movement, will
cause bright orange flames. Wait for dust to settle.

3. For one burner, close the air shutter until some of
its flame jet tips turn yellow-white, indicating insuf­ficient primary air. Then open shutter until whitish
tips disappear completely. Set all burner shutters
to the same opening. Observe to make sure that
no yellow-white tips appear over any portion of
the flame. Small yellow tips at the pilot location are
permitted.

NOTE: This adjustment method gives MINIMUM
primary air setting for safe combustion. DO NOT
attempt to make this adjustment unless burners
are at operating temperature. Adjustment should

e made with burner access panel in final operat-

b
ing position. Use of a mirror may be helpful to
observe flames. Note that burner ports are on top
of main burner tube.

C.Main Burner Ignition Checkout and Pilot Adjustment

1. The pilot flame must not smother or snuff out
when tested as follows:
a. Main burner ignition from cold start-repeat.
b. Continued operation of main burner.
c. Main burner ignition with appliance at maxi

mum operating temperature after prolonged

operation.
NOTE: Observe operation of the pilot burner with
appliance doors in the final operating position.
Use of a mirror may be helpful.
