Laser 60AT
2-14 FOR HIGH ALTITUDE USE
The heater is designed to be used no more than 3000
FT. (900 m) above sea level. No restrictions other than a
maximum length of extension pipes of 10 FT. (3m) with
three (3) bends up to 3000 FT. (900m) above sea level.
For between 3000 FT. to 6000 FT. (900 m to 1800 m)
use, the following procedure should be used:
• Straight - through installation only (no extension pipe).
• Change jumper wire "JX2" (See Fig. 2-13) from "Lo"
position to "Hi" position, this will result in reduction of
fuel flow of approximately 10% or change wire
position to High Altitude post.
NOTE:
All installations over 3000 FT. (900m) above
sea level may require a trimming adjustment of
the fuel flow rate on fuel pump.
When you adjust the fuel flow rate, wait until
unit has been in high burn mode for 20 min.
and follow instructions in this manual.
