Stack Installation
1. Install a barometric damper (NOT included) in the stack if the draft up the stack
exceeds -.08. Draft up the stack must be -.04 to -.06 inches of water column. Check with
draft meter between the top of the heater and damper. The over ire draft should be a
minimum of -.02- check through lame inspection port. Closing the damper door can
increase draft.
2. For optional draft inducers or power vent wiring, See Figure 2. One of these devices must
be installed where back draft is present. In building or correct draft cannot be achieved.
Oil Supply Tubing
1. Use ONLY 3/8” nominal ID copper tubing with lare ittings only on the fuel suction from
the tank to the heater.
Do NOT use ferrule ittings or Telon tape on any pipe-ittings.
2. Keep suction line approximately 6” from bottom of oil tank to prevent suction of sludge.
Drain accumulated sludge and water from tank periodically.
3. Use only an inside oil storage tank to supply heater.
Do not draw from an outside tank,
especially not an underground tank, directly to heater. A separate transfer pump from an
outside tank with proper iltration to the inside supply tank is acceptable and available
from EconoHeat.
4.
T
he fuel supply pump included with heater is to be mounted at tank level or below
(igure 1). This pump turns slowly requiring a number of minutes to accomplish purging
ALL air, if bubbles, skips, even slight pulsations in the oil low from pumps bleeder port is
unacceptable and must be removed assuring proper oil low to heater. Otherwise, the
lame sensor will not see enough lame and heater will lockout.
NOTE: PUMP ASSEMBLY
MUST BE MOUNTED HORIZONTAL.
5. Connect 3/8” oil supply line from the supply tank through the ilter (igure 1) to the pump
inlet located same side as bleeder port (igure 6). Continue oil supply line from pump
outlet to bulk head itting secured to cabinet at left side of burner assembly (bulk head
itting has fuel lex hose connecting it to burner).
