On/Off Switch - resideo VR8215S Notice D'installation

STARTUP AND CHECKOUT
On-Off Switch
The on-off switch settings are as follows:
• OFF: Prevents main gas flow through the control.
• ON: Permits gas to flow into the control body. Under
control of the thermostat and direct ignition module,
gas can flow to the main burners.
NOTE: Controls are shipped with the electronic on-off
switch in the ON position.
Perform Gas Leak Test
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury
or death.
Perform Gas Leak Test every time work is done
on a gas system.
Important
Do not spray soap and water solution on the gas
control. This can damage the control. Do not
use an excessive amount of soap and water
solution to perform the gas leak test. Apply only
to pipe thread areas.
Gas Leak Test
1. Paint pipe connections upstream of the gas control
with rich soap and water solution. Bubbles indicate
a gas leak.
2. If a leak is detected, tighten the pipe connections.
3. Light the main burner. Stand clear of the main
burner while lighting to prevent injury caused from
hidden leaks that could cause flashback in the
appliance vestibule.
4. With the main burner in operation, paint the pipe
joints (including bushings) and the control inlet
and outlet with rich soap and water solution.
5. If another leak is detected, turn the gas control to
off, tighten the joints and pipe connections.
6. Replace the part if a leak cannot be stopped.
Turn On System
Push the on-off switch to the ON position.
Turn On Main Burner
Follow appliance manufacturer instructions or turn
thermostat up to call for heat.
VR8215S,M,T SINGLE STAGE DIRECT IGNITION GAS CONTROLS
Check and Adjust Gas Input
and Burner Ignition
Important
1. Do not exceed input rating stamped on
appliance nameplate, or manufacturer's
recommended burner orifice pressure for size
orifice(s) used. Make certain primary air supply
to main burner is properly adjusted for complete
combustion. Follow appliance manufacturer
instructions.
2. IF CHECKING GAS INPUT BY CLOCKING GAS
METER: Make certain there is no gas flow
through the meter other than to the appliance
being checked. Other appliances must remain
off with the pilots extinguished (or deduct their
consumption from the meter reading). Convert
flow rate to Btuh as described in form 70-2602,
Gas Controls Handbook, and compare to Btuh
input rating on appliance nameplate.
3. IF CHECKING GAS INPUT WITH MANOMETER:
Make sure the gas control is in the OFF position
before removing outlet pressure tap plug to
connect manometer (pressure gauge). Also
move the gas control switch back to the OFF
position when removing the gauge and
replacing the plug. Before removing inlet
pressure tap plug, shut off gas supply at the
manual valve in the gas piping to the appliance
or, for LP, at the tank. Also shut off gas supply
before disconnecting manometer and replacing
plug. Repeat Gas Leak Test at plug with main
burner operating.
NOTE: Check the inlet pressure before adjusting the
pressure regulator.
Standard (S, M) and
Slow-Opening (T) Models
1. Carefully check the main burner lightoff. Make sure
that the main burner lights smoothly and that all
ports remain lit.
2. Check the full rate manifold pressure listed on the
appliance nameplate. Gas control full rate outlet
pressure should match this rating.
3. With main burner operating, check the control flow
rate using the meter clocking method or check
pressure using a manometer connected to the
outlet pressure tap on the control. See Fig. 7.
4. If necessary, adjust the pressure regulator to
match the appliance rating.
5. If the desired outlet pressure or flow rate cannot be
achieved by adjusting the gas control, check the
gas control inlet pressure using a manometer at
the inlet pressure tap of the gas control. If the inlet
pressure is in the nominal range (see Table 6),
replace the gas control. Otherwise, take the
necessary steps to provide proper gas pressure to
the control.
