Caution
Should overheating occur or the gas supply fail to
shut off, do not turn off or disconnect the electrical
supply to the pump. Instead, shut off the gas supply
at a location external to the appliance.
Attention

peut être coupée, ne pas couper ni débrancher
l’alimentation électrique de la pompe. Fermer plutôt
le robinet d’admission de gaz à l’extérieur de
l’appareil.

système de régulation du débit du gaz ou à
l’appareil. Toute modification non autorisée est
dangereuse et entraîne l’annulation de toutes les

Before starting your boiler, be sure that all of the
functions and limits of the JVS and JVT boilers have
been set according to the previous section of this
manual (Section 7.2). Follow the instructions outlined
below. Read and follow all safety instructions first. A
more detailed set of lighting and shutdown
instructions are listed on the label located on the
boiler.
NOTE: If your boiler is configured to operate on LP
gas and the LP tank runs out of fuel, turn off gas at
the boiler. After the tank is refilled, the boiler must
be relit following the instructions found on the boiler.
DO NOT attempt repairs on the gas control or
heater. Tampering is dangerous and voids all
warranties.
WARNING
If the information in these instructions are not
followed exactly, a fire or explosion may result
causing property damage, personal injury or death.
AVERTISSEMENT
Assurez-vous de bien suivre les instructions
données dans cette notice pour réduire au
minimum le risque d’incendie ou d’explosion ou
pour éviter tout dommage matériel, toute blessure
ou la mort.
7.3.1 Lighting the Boiler
Lighting instructions are as follows:
1. Verify that the pump system is operating
properly:
a. Shut off the manual gas valve located
outside the boiler.
b. Raise the wall thermostat high enough to
call for heat.
c. The pump should come on immediately. If
it doesn't, test the electrical circuits.
2. Pilot Information:
a.
The JVS boilers do not require manual
lighting. The pilot is controlled by the
automatic ignition system.
b. The JVT boilers do require manual pilot
lighting. For access to the pilot burner,
remove the louvered airbox cover by
loosening the two thumb screws.
c. Different models of the JV boiler utilize
various gas valves. Although the gas valves
may have different control knobs, they are
all similar in operation. The JVS gas valve
has a two-position knob, ON and OFF. The
JVT valve has a three-position knob, ON,
OFF and PILOT, some models come with
extra push-button (see Figure 12).
