Lighting the Oven
This oven is equipped with an electronic ignition system. This system can operate with 2 D batteries or it
can be used with a 3 volt DC adaptor. The batteries should last between 6months to 1 year depending
on use and where the oven is placed (extreme heat and cold temperatures will decrease the life of the
batteries). Please check battery frequently to make sure its appearance is normal. We recommend
battery replacement every 1 year from time of purchase. HPC Hybrid Oven also has an adaptor that can
be used to electronically ignite the pilot and operate the oven gas burner. This adaptor has to be plugged
in an 110v GFCI outlet.
The oven’s gas burner will not operate unless the safety pilot is on.
Please follow these steps to turn your burner on:
Make sure burner is clear of ashes or debris.
Make sure valve control valve is on off position.
Turn on valve on LP cylinder or natural gas shut off valve
Turn valve in the oven control panel to off position.
Turn electronic igniter switch to ON. It might take 30 to 60 seconds for gas to travel from tank to
pilot the first time you start your oven)
Once pilot is lit, turn the gas control knob from OFF position slowly to regulate burner flame.
Turn gas regulator knob to OFF and place small pieces of dried hardwood on burner. Regulate
gas flame so wood can ignite. Leave gas on.
Once wood has ignited and smaller pieces of coals have formed, with the back of brush push
wood to center of oven to heat the hearth. Then place more wood on top of coals.
Leave the gas line ON. It will do a couple of things
1. Keep the oven hot and the flame steady
2. Keep the smoke to a minimum
(If you have too much smoke because the fire is dying, wood is wet or not enough wood –try turning the
gas up a bit, it usually burns off the smoke.)
Your oven should be hot enough to bake a pizza in about 30 min. (obviously cooler temperatures
take a bit longer) the use of our insulating blanket should also help with heat retention.)
Different locations in the oven heat up differently –The hearth at its hottest temperature gets
around 800°. Inside the dome on top-over 1000°. The outside of dome on left side (where the
burner is lit) can reach about 400° The dome on the opposite side of the burner can reach about
300°.
Gas control knob. Turns flame up or down
Pilot has to be ignited for burner flame.
On/Off switch

14
Lighting the Oven
A good way to test the hearth to see if it is hot enough to bake a pizza –throw some flour on
hearth and it should burn within 1-2 seconds. If not, then with brush bring the wood back to center
of oven, add more wood and let it burn hotter. Then move it to the back of the oven.
Brush center of the hearth
Place pizza on hearth and turn pizza ¼ turn every 30 seconds or watch for golden brown on
cheese and dough.
Remove pizza and enjoy.
To Use a Grill
Follow same steps to start oven and hearth
Place disposable aluminum pan on hearth to catch grease.
Insert grill rack with a hot pad/mittens
Add grill rack to oven (It’s a good idea to spread some olive oil on the grill rack top before putting
it in the oven.)
Add food –Watch it sizzle
Remove. Enjoy.
If your food doesn’t need a grease pan, you can leave ambers on hearth and slide grill rack on
top of it.
You may grill, bake, or use a skillet on top of the rack. The possibilities are endless.
We suggest the use of an infrared thermometer if you want to do more detailed temperature
control like breads and chicken.
We suggest baking bread in the front of the oven where the temperature is around 300-400°.
We suggest smoking after cooking is complete. Close the door and let the fire die out. Adding
some of your favorite smoking wood chips to the “died-out fire” will create smoke in the oven and
it will remain circulating inside the oven. Smoking should be done at lower temperatures. Oven
door temperature gauge should be pretty accurate in displaying oven temperature.
Heat control can be achieved by decreasing the amount of wood, decreasing gas, closing the
door (Door works as a damper-less oxygen entering oven, less fire).
BAKE
You may also bake bread in the oven. Turn on gas and leave door half open. Regulate heat. Bake.
Whenever you are done using oven, make sure LP tank is off and let oven cool down.
Do not place outdoor cover on till oven has cooled down.
Careful! Door will be hot. Only touch the wooden handle.
CAUTION
Never place door without door vent whenever gas is turned on. It might cause an
explosion. If smoking, remove door vent turn gas completely “off” at gas control knob
and at the LP tank/shut off valve.

FirstFiring
HPC Hybrid Oven ovens are constructed for optimum performance. It is important to heat
the oven gradually if water has come in contact with the oven.
If water gets absorbed by oven, small cracks might appear if quick oven heating occurs.
About your refractory oven:
A refractory material is one that
retains its strength at
high temperatures. Your oven’s
refractory material can withstand
temperatures up to 2400 degrees.
Unlike other ovens in the industry
that are multi–pieced and joined
together with mortar, your oven is
shaped as one piece allowing it to be
moved maintaining its shape and
aesthetics of a century’s old oven.
This shape enables the best
functional heat distribution in the
oven. Its two inch wall thickness
reflects enough heat back to the
inside of the oven, and the
temperature on the outside of the
oven remains one third of the inside
temperature; optimizing heat
retention .
3 heat sources and
temperatures that exceed
1000°
Important information:
Once your oven is poured and
removed from its mold, it goes
through a drying process that allows
water to evaporate. Glass is
mortared using a proprietary
formula that will withstand the high
heat generated during normal
operation. In order to properly cure
the glass to the oven a heat up
schedule should be properly
performed. During your first oven
firing, small water molecules that
remained trapped in the refractory
during the drying process will come
out in a vapor form.
WOOD-OAK-ONLY!
Simple and very important for proper
operation.
-Use at least 1 year dried , debarked
1 1/2 to 3 inch diameter, 12 to 14
inch long OAK. You’ll have
consistency during operation, no
smoke, no popping ambers on to
your food, intense heat and a great
smell.
Your oven’s first firing:
First time firing-heat up with gas only.
1. Start with a 1/2 inch very low flame on
the gas burner for 2 hours.
2. Raise flame to 1 1/2 inch in size for 1
hour.
3. Increase flame to 2 1/2 for 1 hour
4. Stoke with kindling on the burner to
continue to raise oven’s temperature
for another 1 hour
5. Do not use door during first firing
6. Complete at least 5 hours for the first
firing
Important:
Follow oven curing instructions to maximize the
longevity
of your oven.
Do not
heat up the oven too quickly. It will
damage the tile.

Natural gas connection
The Forno Series can be purchased to be used with natural gas.
This connection has to be done by a licensed hearth installer.
It’s very important to have correct diameter gas lines for desired oven output.
A shut off valve should be placed between the house and the oven.
Connect an approved Natural Gas line to the right side of the oven, located on the underside of
the oven hearth plate.
Make sure all the connections are tight and comply with local codes. Turn gas shut off valve on
and check for leaks.
Follow how to start the oven instructions.
Natural Gas needs to
be connected here.
The installation of this appliance must conform with local codes or, in the absence of local codes , with either
