Are you talking about not boiling your top off Water? If so you should be fine.
Yes this is what I'm referring to.
First thing I did was sanitize all my instruments and holding tub then sterilized using Iodophor.
Then I followed these instructions from the Brewhouse kit I purchased.
Date_______________ S.G.___________ (1.040-1.050)
PRIMARY FERMENTATION
Sanitize and rinse the primary fermenter, spoon, hydrometer, test jar, measuring cup, thermometer
and kitchen spoon.
1. Add contents of package #1 to the sanitized primary fermenter. NOTE: Package #1 contains a pH
adjuster and essential. If it is omitted the finished beer will not taste good. Do not make the kit without
it.
2. Add 8 litres (1.8 Imp. gallons) of room temperature water (18-23°C[65-75°F] ).
3. The spout at the top of the box allows for easy pouring. Secure bag spout into box top.
4. Place box upright and remove cap. Tilt box and pour wort into primary fermenter. Stir vigorously for one minute.
5. Take and record specific gravity (S.G.) now. (my reading was 1.34 sg)
6. Sprinkle yeast on the surface - Do not Stir
7. Put the lid on the fermenter and store at room temperature (18-23°C [65-75 °F]). If possible, raise the fermenter approximately one meter (3 ft.) onto a strong counter or table to avoid disturbing the
sediment when racking.
When I looked at the beer this morning there was hardly any head on it, maybe a 1/4" to 1/2". When I had put the yeast on, there must have been a good 6-8" of head.
So to answer your question about the boiling, I didn't boil anything as it wasn't written in the instruction as it came in a bag full of liquid.
"Over 3 days the beer will develop a head of foam, indicating that fermentation is proceeding. When
this head of foam drops (Day 3)"
