Tips for Enhancing Your HOTTAP Experience
- If using a small 1-pound gas canister, place it in a bowl of boiled water. This maintains a consistently hot shower temperature, as occasional drops in temperature can occur.
- On windy days, position the shower area away from the wind. And construct a sturdy windbreak around the heating unit. Neglecting these steps may extinguish the flame, necessitating a restart.
