Section 16 - Oil Tanks - Johnson Controls YORK YPC Series Installation Manual

FORM 155.17-N1
ISSUE DATE: 4/1/2013
It is recommended that prior to installation, NFPA-
31 and all other national, state, local and other appli-
cable codes be reviewed to ensure total compliance
with their requirements including, but not necessarily
limited to, the use of anti-siphon valve(s), oil safety
valve(s) (OSV), or other acceptable means to prevent
siphoning of the oil when tank is above burner level.
Even if such devices are not required by code, they
should be considered good installation practice, and
are mandatory when the tank is above the burner level.
If the oil storage tank has been used with fuel heavier
than #2 fuel oil, the entire system should be thorough-
ly cleaned and flushed before filling the tank with the
new #2 fuel oil for the first time.

SECTION 16 – OIL TANKS
If iron pipe oil lines are used on underground tanks,
swing joints utilizing nipples and elbows must be used
and joined together, making certain the piping con-
nections are tightened as the tank settles. Keep swing
joints in the suction and return lines as close to the
tank as possible.
Underground tanks should be pitched away from the
suc tion end of the tank to prevent sediment from ac-
cu mu lat ing at the suction line entrance. Install the suc-
tion line a minimum of 3" from the bottom of the tank.
Before starting up the system, all appropriate air and
oil leak tests should be performed. Make certain that
the tank atmospheric vent line is unobstructed.
