What form is used to pull an oil burner permit
CMR.4
What size pipe is used to CrossConnect tank outlet piping
1/2 inch
When is an oil safety valve used
On an existing installation when a burner boiler furnace or tank is replaced.
When must you install a draft regulator
When not exempt by manufacturer
A fuel oil storage tank cannot be installed:
In the furnace room 5 feet within heating unit
What temperature does a thermal wheel automatically activate at
165°F
Who inspects an oil burner installation
State fire marshal
Any valve used on a oil burner install must be:
Fusible valve
What type of boiler must be equipped with a low water cut off
Water boilers over 500,000 BTUs & all steam boilers
All new oil burner controls must be:
Interrupted ignition
How far must continuous concrete slab extend beyond the tank perimeter
8 inches
All protective control and emergency devices shall be series connected from the
electrical distribution panel:
Through the emergency switch, through the terminal switch, to the service switch in the
ungrounded line conductor
If the ceiling above the burner boiler or burner furnace exceeds 12 feet in height, and
additional thermal switch shall be installed at a height of_______ and connected in
series with the lower switch.
10 feet
An oil safety valve can perform the following functions:
Reduce pressure from its inlet to its outlet & prevent gravity flow
Fuel oil filters should be selected for the following:
Micron range & flow rate
Ultra low sulfur fuel has no benefit to a fuel oil system
False
To ensure the best mechanical seal throughout a fuel oil delivery system the following
should be used:
, Flared fittings and pipe dope
Adding a pre-heater to an oil burner will
Allow oil with a high paraffin base to flow more easily & decrease the viscosity of a fuel
oil
True
The safety switch of a primary should be checked by:
Closing a oil valve, pulling a cad cell lead, disconnecting the motor lead.
All the above
Doing a combustion pre-test on a oil fired appliance will not tell you anything, that's why
nobody does them:
False
Power must be provided to a electric blower control board on terminals:
L1 & L2
What is the most common source of water in oil tanks:
Condensation
The home for bacteria growth and sludge in the bottom of oil tanks is:
Water
Fuel units (oil pumps) preform the following function:
Move oil from the tank to the burner and deliver it at a constant regulated pressure to
the nozzle
If the operating vacuum reading is significantly above the calculated vacuum you
probably have
A clogged oil filter
The best way to clear a clogged line is to
Use a hand pump to clear the blockage
It is best to connect fuel units as a one pipe system instead of two pipe because:
One pipe leads to longer filter life and eliminates leaking return lines
The key final adjustment for most oil burners is
combustion air
High pressure atomizing burners
Pressurize the oil to turn it from a liquid to a vapor than ignite it
An advantage of flame retention burners is
They're high stack pressure enables boilers and furnaces to have tighter heat
exchanger passages
Dirt or lint build up in the bevel of the burner fan blades will
Reduce the amount of combustion air
All petroleum products are chemical compounds of
hydrogen and carbon
The pour point of #2 oil is
The lowest temperature at which oil will flow
Sulfuric acid in combustion gases can
Create scale buildup in the heat exchanger
As heating oil gets colder it's viscosity thickens
Increases
Energizing the ignition circuit during the entire burn cycle reduces
Ignition component life
