PAR MESURE DE PRUDENCE, LISEZ CE QUI SUIT AVANT
DE FAIRE FONCTIONNER L’APPAREIL
MISE EN GARDE
Si vous ne suivez pas ces instructions à la lettre, un incendie ou une
explosion pourrait se produire et causer des dommages matériels,
des blessures personnelles ou même la mort.
A. Cet appareil n’est pas doté d’une veilleuse. Il est
équipé d’un dispositif d’allumage qui allume
automatiquement le brûleur. Ne tentez pas
d’allumer le brûleur manuellement.
B. AVANT D’UTILISER, vérifiez s’il n’y a pas
d’odeur de gaz près de l’appareil. Vérifiez s’il n’y
a pas d’odeur de gaz près du plancher, car le
gaz est plus lourd que l’air et peut se déposer
sur le plancher.
QUE FAIRE EN CAS D’ODEUR DE GAZ
• N’essayez pas d’allumer n’importe quelque
appareil que ce soit.
• Ne touchez pas à un commutateur électrique.
N’utilisez pas le téléphone de votre résidence.
• Appelez immédiatement votre fournisseur de
gaz en utilisant le téléphone de votre voisin.
Suivez les instructions de votre fournisseur de
gaz.
• Si vous ne pouvez joindre votre fournisseur
de gaz, appelez le service des incendies.
C. Fermez la soupape d’arrêt de gaz (située au-
dessus de la commande de gaz multifonctions)
de sorte que la poignée soit perpendiculaire au
tuyau de gaz. Si vous ne pouvez tourner la
poignée à la main, n’essayez pas de la réparer.
Communiquez avec un technicien de service
qualifié. Le fait de forcer ou de tenter de réparer
la poignée pourrait causer un incendie ou une
explosion.
D. N’utilisez pas cet appareil si l’une des pièces a
été plongée sous l’eau. Communiquez
immédiatement avec un technicien de service
qualifié afin qu’il inspecte l’appareil et remplace
toute pièce du système de commande et toute

SECTION 1.
Caring For Your Summit
Your Summit will require very little
maintenance. However, as with any fine appliance,
there are certain steps you should take to insure
continuing optimum performance.
1A. General Care
Keep your Summit area clean and free from
combustible materials, gasoline and other flammable
vapors and liquids.
If you desire, clean the jacket surfaces with a
damp cloth and mild soap. Do not use flammable
cleaning materials.
Keep vent terminal free of obstructions — do
not pile snow against vent terminal.
1B. Annual Inspection of Flue and Vents
You should visually inspect the vent pipe once a
year. Should any deterioration exist, have the affected
parts replaced.
1C. Shutting Down the Summit Boiler
If the need arises to shut down your boiler, the
following steps are required.
1. Switch off main disconnect switch (located on
left side of unit).
2. Close manual gas shutoff valve above
combination gas control valve (inside unit).
3. Close main manual gas valve.
4. If freezing is anticipated, drain Summit and be
sure to also protect building piping from
freezing.
The above steps may require qualified service
personnel.
1D. To Restart Your Summit
Should the need arise, you may have to restart
your Summit. Follow these steps:
1. Momentarily depress reset button on top of
control panel
2. Turn up the thermostat to call for heat.
3. In approximately 2 seconds, the blower will
operate and ignition will occur after 35-40
seconds. It may take as long as 2½ minutes.
4. If it does not occur, wait 5 minutes and then
repeat steps 1 through 3.
5. If, after three attempts, you still do not get
ignition, shut down your Summit and call your
service man.
If drained, follow these steps:
1. Follow “Installation Manual” for proper filling
and purging.
2. Turn on main manual gas valve.
3. Remove front cover and turn on manual gas
shutoff valve, above combination gas control
valve.
4. Switch on main disconnect switch, depress on/
off button on front of control panel, and depress
black reset button on top of control panel (pump
and blower will start and igniter will be
energized, after 35 seconds the gas valve will be
energized, and ignition will occur). If ignition
does not occur within 2½ minutes switch “off”
main disconnect switch, wait 5 minutes and
switch “on” again. If after three attempts ignition
does not occur, initiate shutdown procedure and
call for service.

1E. Annual Inspection of Condensate
Drain System
Visually inspect the condensate drain lines. If
either clear plastic line appears to be full of
condensate (water), loosen the nut on the jacket that
retains the line and remove the line from the jacket
and clear any obstruction from the line. Replace line
and tighten nut.
1F. In the Event of Power Failure
The Summit cannot be operated during an
electrical power outage. If there is an extended power
outage with danger of freezing, then the Summit (and
all other water systems) should be completely drained.
When draining the Summit, turn off gas and turn off
main power switch. When replacing in service, refer
to start-up instruction for proper filling and purging.
1G. Full Service Every Three Years
In addition to the annual visual inspections by
the owner, a qualified service agency should conduct
a detailed inspection of all flue product carrying areas
of the boiler and vent system. This should be done in
accordance with the service instruction in the
“Installation and Operating Instructions Manual” for
the Summit.
Figure 2. Components Identification.
WARNING
Do not use this boiler if any part may have been
under water. Immediately call a qualified service
technician to inspect the boiler and to replace any
part of the control system and any gas control which
may have been under water.
WARNING
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.
AVERTISSEMENT
En cas de surchauffe ou si l’admission de gaz ne
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.
FOR SERVICE
Contact your installing contractor, gas utility, Laars
dealer or call Laars for the nearest authorized
representative in your area.

Message
1H. Trouble Shooting - Fault Codes
The Summit boiler is controlled by a Pactrol
integrated boiler control (PCB) which provides seven
fault codes with eight memories. To obtain fault
messages press-in on the message center fault button
until the first fault code (FL1) is displayed. The last
recorded fault will appear e.g. F-4 (flow thermistor
faulty - open or shorted). The control will then
sequence through all eight memories, indicating
alternately the fault number and the fault code (FL1,
F-?; FL2, F=?; …, FL8, F=?). The fault number in
fault code FL1 is the most recent fault.
1H-1. Fault Code Identification
The following seven fault codes may be observed:
F- Error corrected, control in auto reset period
(10 seconds)
F-0 No fault has occurred
F-1 Error occurred while reading fault logic of
main control
F-2 Over heat thermostat (Boiler or Flue) has
operated (open circuit)
F-3 Fan fault
F-4 Flow thermistor faulty (open or short-
circuited)
F-5 Differential Pressure Switch Contacts
opened
