G. ELECTRICAL
The installation must
be
wired
and GROUNDED
in
accordance
with local
codes or
in their
absence,
with
the
National
Electric Code ANSI/NFPA No. 70-
1987
or
latest
edition.
For
the 120 VAC wiring
to
the burner,
use solid
copper conductor wire not lighter than #14 AWG. lf
a
fused
disconnect
is
used, it should be
fused
for a
minimum
of
15
amps.
CAUTION:
Each installation must include
suitable
limit controls. Existing oil burner
combination limit
and operating controls are normally
not
suitable
for
gas
burner use.
CAUTION:
The burner is
equipped
with it's own 24
VAC
transformer. Do
not
add any
24 VAC
power
consuming device in
the
24 VAC control
circuit of
the burner, as it could overload the transformer.
Set
the room thermostat
"heat
anticipator" for the
totaf current draw of the 24
VAC
burner operation
circuit.

GAUTION:
Label
all
wires
orior
to disconnection
when
servicing controls. Wiring errors can cause
improper and dangerous operation.
Verify
proper
operation after
servicing.
NOTE: lf
any of
the
original burner
wiring must
be
replaced, it must
be
replaced with #18
AWG 105 degrees
C
wire or equivalent.

H. MAIN
BURNER
ORIFICE SIZING
AND INSTALLATION
The HSG200 and HSG400
power gas
conversion
burners are approved for use with natural
and
propane
gas
only.
The HSG200 and HSG400
burner
models
are
shipped
labeled
and orificed for natural
gas.
To
conveft to
propane gas
and/or increase BTU/HR
(kcal/Hr)
input on natural or
propane
gas,
an
orifice
kit is
supplied
with
each burner
with the
orifices
shown
in Figure
10.
When selecting a desired BTU/HR
(kcal/Hr)
input,
figure 140,000 BTU's
per
gallon
of
oil input. For
example:
furnace or
boiler
rating
of 0.75gph at
100
psig.
The
0.75 x
140,000
=
105,000
BTU's input
rate. lt may be
possible
to reduce the firing rate on
natural
or
propane gas
15%
lo
20o/",
as
most
older
appliances are oversized for the heating load.
(2.83875L
x 9356 kcal
=

To
remove
or
interchange main
orifice discs
refer
to
Figure 15
(Page
16).
1. Remove slotted orifice cap,
ltem #40, making
sure orifice
cap
gasket,
#39,
stays
attached to
orifice cap and
is not
damaged.
2. Remove orifice
spring,
ltem #38, to access
and
remove orifice disc. ltem #42.
3.
Install desired orifice from Figure 10, making
sure
it is
seated
flat in
the orifice
holder,
ltem
#37.
4. Replace orifice
spring and securely tighten
orifice cap against orifice cap
gasket
in orifice
holder.
