Model Selection
The
ZIMMER
is available in three versions – One propane Model
(e.g. Z40P) and two LPG models (e.g. Z40L and Z40S).
The difference between the L, P and the S models are the
inlet valves. The inlet valve operates on the thermodynamic
properties of the specific gas (either LPG or commercial propane).
The valve expects to see the vapor exit the vaporizer at 8
°
C (15
°
F) warmer than the boiling point of the respective gas. The unique
function of the valve is that it senses both pressure and
temperature to truly predict the boiling point.
The valve is clearly marked with a sticker indicating whether it is to
be used with LPG (70/30), Propane or 50/50 (LPG).
Propane version (e.g. Z40P) – See Table 1
• Use with 85% or greater commercial Propane.
•
Never use propane which exceeds 15% Butane
.

LPG version (e.g. Z40L) – See Table 2
•
Full capacity is based on LPG containing 60-80% Butane.
• Never use LPG which contains more than 80% Butane.
• Using the LPG version with LPG containing more than 40-
60% Propane will decrease the capacity of the vaporizer.

Especially in warmer environments.
